To be clear, not talking about this community, obviously ๐.
What's the point of writing down rules, if mods just do what they want?
But I suppose that's the risk you take when you call someone a liar in a small community; they might be a mod.
Edit:
I'm not trying to say that mods suck, they perform a useful and often thankless job. Just that it can be difficult for small communities to get a healthy number of good mods, which can become a problem.
Sorry, but that's crap. Questioning the credibility of a liar is not automatically fallacious reasoning or an ad hominem. Attacking their character instead of arguing against their points is an ad hominem fallacy. Pointing out the consistency of lies from a single source and then extrapolating out to question the validity of future statements of fact is rational, logical, and reasonable. It's perfectly valid to label a liar when they repeatedly tell lies, as long as you can support the label by proving they are lying.
