Basing this theory on the MASSIVE influx of "muh joo" posts since registrations reopened:

Close the site.

Monitor every single post.

Delete accounts that they are sure are "muh joo" shill accounts (retain all old goat accounts who are genuinely antisemitic, the target is the shills not the lost souls).

Once most shill accounts have been wiped then open up registrations again.

Record where new registrations originate.

Do something with the data about new registrations and their origin.
