I agree with six, no need for a dislike button. If we respectfully disagree with someone, it is better to quote the post and explain why.
I've been here a while and really had no true beef with anyone by doing this.
Dislike buttons would just turn the forum into a series of petty squabbles in short order IMHO.
This.
To the OP: IMHO, the best way to educate people about poor experience and bad advice, is to quote the original post, and then explain exactly why it is wrong.
That is the best way to give other people the correct answer to a given problem.
For example, we have seen people posting here in the "sub-ohm" forum, stating something like "I do not even know Ohm's law, but that's OK"

A simple "dislike" button is not enough to explain people why sub-ohming AND not knowing what you're doing can lead to disaster - and to the "ANTZ ammo" you spoke of.
Plus, it could turn this great forum into an hostile one. Today, if you "dislike" someone's post, you have at least to explain WHY - not just "because"...
