I believe you're suffering from a confirmation bias here.
Yes, some people play silicons to fight antags. As Nerfection said, this is not fine. Ahelp them and administrative actions will be taken.
However, I still maintain that more often this is an outcome of an otherwise boring gameplay. Furthermore, adding actual tasks for AI would already support taking additional administrative actions against them. If AI is hunting antags at the expense of doing its job, that is a clear rule break.
I'm sorry, but slapping more OOC padding on antagonists will not improve the gameplay. OOC padding inevitably breeds even more resentment.
"Toxic gameplay", as you say, is a result of your own vitriol. You refuse to learn, improve and adapt. You want admins to save your greentext. It's quite literally a buzzword (phrase?).
Even if we agree, hypothetically, that gameplay is toxic, this only further reinforces necessity for mechanical solutions to the problem. Policies could fix toxic behaviours. Toxic gameplay requires different solutions, since the issue clearly lies in how the game plays.
You're also plainly wrong about my suggestions not being counters. AI has no way to counteract sabotage of its equipment outside of having an engineering cyborg or hoping crew engineers help it.
I cannot believe you're making me defend silicons, you know? My street reputation of a sillycon hater is ruined. Anyway, I wrote my rants and don't plan on inflating the thread any further, just in case someone actually wants to read through it.
Good luck, even if I largely disagree with how you are trying to fix the problem.
