One very common shilling tactic I have seen here is accounts that have been inactive for long periods suddenly going live to attack a thread or post. I propose a few countermeasures to possibly counteract this:
Temp restriction no more then 10 posts a day for a week for accounts 4 months inactive or more, must be active for at least a good portion of a week to remove restriction.
Marking all posts a 4 month or more inactive account makes, flagging to regular users that it was a hibernating account.
Or if the shilling gets really bad, all accounts inactive for more then 4 months nuked and need to resign up.
This honestly would make shilling just a bit harder without silencing Voat's platform of free speech, and make blatant brigades easy to spot and highlight.
