I'm not really shocked /r/conservative is suspected of doing this. That sub has some really shitty power tripping mods. They routinely ignore their own rules, shitpost about the same topics constantly, abuse their authority to sticky threads and even responses in other people's threads, etc. And one of the worst things is that the same small handful of mods are mods of several of the conservative leaning subs at once, so if you piss one off in one of them, plan on getting banned or attacked in all the rest.

The enemy of my enemy is my friend. Islam seeks to destroy western civilization, and so does the left, so they don't mind working together for that end.
