Mod action complaint posts

Desktop, any. Just out of curiosity, what do you personally do in this case? It happens very rarely for me but someone makes a attention-seeking/complaint post about a mod action because their content is clearly against sub rules.

I have seen it in other subs as well and people will 'rise up' and agree with OP, making the whole situation unnecessarily escalated and frustrating. Do you remove the post, issue a ban, ignore it?
