Personally, I think some people deserve bans/mutes and its fair. For example, anyone who scams other people out of money or pokemon deserves a ban.
Other people, however, get muted or banned for in my opinion silly reasons like they made a "offensive" joke. I've seen entire discussions about vampires and Trump (and sometimes both together) yet one small Dracula joke can get people banned.
Basically, I say keep the bans/mutes for those who deserve them like scammers.
