You likely won't be banned for merit farming but that user was banned because he has been farming hundreds if not thousands of accounts with bots in the Chinese section going on years and has already had hundreds banned, so he was banned for ban evasion but was caught or exposed because he was farming merit between his alts.





I think most people will consider it cheating if you give out merit to alts for any old post. Merit is meant to be earned and was implemented to try stop farming accounts with shitposts, so I'd say just giving merit to your alts is cheating the system.
