It seems that the Antifa has went from giving racists and anti-semites what they deserve to just stalking people.
Also, the owners of that site claim to be anarchists, but they censor whoever they don't like.
Anarchism is in the libertarian left. And libertarianism is supposed to be about freedom. The hypocrisy just hurts.
So, yeah. If you ever troll that site, use a VPN.
