But if you don't report his posts, his account will not be banned. If you want him to be banned, keep reporting
If Mods would be less forgiving for spammers, none of this would be necessary. So maybe it's necessary for spam to get worse before Mods start banning them again.
This comes to mind:
moderators are becoming lenient in moderation, number of banned users reduce.
Just a thought: do Mods earn more from 1 banned account, or from 40 deleted posts?
