Spamfilters on /polru/ and a bug. Anonymous 07/13/2026 (Mon) 21:40 [Preview] No. 30318 [Reply] [Last 50 Posts]
1. https://endchan.org/.static/last50.html?b=polru&t=880626
in the last50 view the Catalog button is broken, leads to 404.
2. Make a board owner option to limit count of new IPs per timeframe after that the option to either (see reply):

2.1 Give a very hard captcha every post during the ratelimit.
2.2 Fully block "brand-new-ip" posters.

It prevents immediate ban evasion for more than 3 times per row. Normal users don't rotate IPs 5 + times per hour. So a spammer in the worst burns 3 IPs if the limit is 3 IPs per 1 hour.
If possible, bypass "known" IPs that posted at least once last week OR IPs that have captcha bypass.

I see it all the time, actually, there are adequate posters that do that

We are going to upgrade the database on May 6th. We'll proceed in four steps:
1. backup the database;
2. do the upgrade;
3. ???;
4. PROFIT!
The whole process could take 12-24 hours downtime.

When the site is down you can hang out on https://wrongthink.net/endchan

why arent tripcodes working/saving in the name field?

Maybe. We'll see.

Yes. Software gets updated by the developers, database software (in our case Mongo) is the same. So we updated from one version to a newer one.

Early deleting posts redirected to main page of board. It was so inconvenient. I closed the tab after deleting. In advance I hold a few thread tabs.
Now flood posts is deleted easily and convenience. Thank you very much!



Selective block by user-agent string for boards owners. Anonymous 06/16/2026 (Tue) 12:05 [Preview] No. 30276 [Reply] [Last 50 Posts]
I am user of /polru/. There is a ban evader who keeps posting bait by changing IP (text posts). You already made lock for unknown users, now make so it can use the simple fingerprint of POST request (e.g. DNT header presence, Sec-GPC header presence, user agent string all in combo) so board owners can block their fingerprint if the post count is lower than N posts. Check req_sig in 4chan source code leak and browser_id to see how desuwa operates it on their side.

Good evening admin๏ผ
Could you please help me delete a thread?
My ID is exposed by mistake in this thread and the poster who is a friend of mine didn't set the code before he create the thread, so he cannot delete it.
This make me very nervous. Could you please help me to delete it?

Thank you very much!

Deleting the whole thread sounded excessive but removed the media. Scrubbed it from the database too.

As a newish phenomenon we're getting DMCA requests now and then. It happened enough times to dedicate a thread for it, a quick explanation and thought.
When we consider a DMCA request we check if the subject in question satisfies fair use:
https://fairuse.stanford.edu/overview/fair-use/what-is-fair-use/
In short we take a look if the posts, the thread can be considered as commentary, criticism, or parody. If we don't find this aspect of the thread prominent enough, we have to comply to the take down request. If this happens we might not give a notice to the affected poster or board.

Personally here I wanna encourage our posters to do creative work, it can be more satisfying and entertaining.

Reminder that you have a legal obligation to respond to ALL DMCA requests.

If you ignore a valid notice, you lose your Safe Harbor protection which opens the door for copyright owners to sue you due to you being liable.

This extends to hosting content and LINKING content -- which I believe is already an issue on /agatha2/

https://www.copyright.gov/512/

Given enough time and the right legal mind, that board itself (endchan by extension) is open for a class action lawsuit if DMCA notices are not taken seriously and responded to in a reasonable timeframe.

Someone might even be working on something like that already...

We do take care all DMCA requests.
There is no time limit how "quickly" we should act even if you write a time limit in there. If you see we haven't take care your request and you feel it's getting long write a note for us to check the emails, it's possible we missed it.

Almost all vpns are banned for spam. So when endchan is blocked in your country you either use tor (not very convenient) or use IPs from some shitty country with ping 500+ which are not banned yet

It's true, most popular imageboards will straight block the IP range of major VPNs

You could try experimenting with the file size limit, set it to 1Kb or something. Not sure the correct syntax.
I think if you set the maximum files to 0 it will set it to the maximum possible.
Perhaps restrict allowed file types to I dunno what, txt...

>Issue 1
Having some trouble with linebreaks spreading out. Seems to do it sometimes but not others, not sure why.
>>>/cumg/36 >>>/cumg/37

>Issue 2
Code tags seem to escape into greentext when $ is used.
>>>/cumg/16 >>>/cumg/15 >>>/cumg/19

>Issue 3
The captcha button has no reload button in the reply pop-up. It doesn't always reload automatically, in turn causing the user the need to refresh the page.
>During the refresh, they may lose their text, however it seems to stay but the file they had attached gets unattached.

>Suggestion 1
Consider wrapping the site with IPFS for archival/resiliency.

I think we missed your post due to the flood.
Those options control how "wide" of a subnet gets banned. Narrow is /24, wide is /16.
Let's say the IP is 12.24.232.198
Then the narrow range is: 12.24.232.0
The wide: 12.24.0.0
Here's wikipee article about the topic:

It seems to me the "Scrub media (remove image from site)" option when deleting posts is no longer working correctly. When I delete posts with this option checked the files are no longer removed from the server as they were before and still remain accessible with the direct link to the image. This is a problem.

I'm not aware that BOs/BVs could scrub. I thought scrubbing is a global option (since it could effect more than one board.)
Board staff can use the remove media, to remove just the media from the post. This doesn't delete it from the db ofc.

I'm pretty sure it used to work even as BO/BV. Because before when I deleted posts with that option checked, the image could no longer be accessed even if someone had the direct link.

Maybe we just scrubbed those. We do vet orphans and there's automatic deletion too. Also if it's a cp spam, that posted across the boards, it could happen that you delete on your board, and right after we delete (we always use scrub in those cases) then it could seem you scrubbed.
