You poor thing if you think any of these suggestions are a reasonable way to "fight back". 99.9% of it is automated, you aren't messing with anyone, and no one is there looking at the screen. A computer program doesn't care if you insult it, ostracize it, spam it, or even block it. It doesn't have feelings and won't stop what it's doing just because you don't like it, or because you told it to do so, or because you pointed it out to everyone. You are literally shouting at a wall.

The only reasonable way for the average person to "fight back" is to report spammers and bots via the in-game support ticket system. Most other things are a waste of time and effort.
