For now, I am just making a quick response to notify a bit.
Here in Spain, it´s 5 PM, and so far, I have not noticed anything different in /mlp/. I had been informed several times about it but as for now, the biggest highlight in the board is the comic of this cutie pie. I am not noticing any big increase in activity or anything really out of the ordinary.
Maybe it will happen in a few hours when the US goes completely in activity and we will notice something.
As for /pol/ or /b/, I haven´t lurked over there, so I cannot talk about them. As for now, ponies are in a safe zone or calm before the storm at least, I will reply tonight to the posts.
