Currently, as everybody knows, cheating accusations in the forum are forbidden. The reason put forward by moderators is that such accusations can damage the reputation of players.
It's a notion taken from the offline world. If your reputation is damaged in real life, you can lose your job, social standing etc. Now for a simple question: if your reputation on this server is damaged, what can you lose? The answer is equally simple: nothing.
Think about it. In real life, public opinion has weight and influence. Here it doesn't, since all the decisions are made by a handful of people called the moderators. As they have repeated a zillion times, moderators react only to official e-mails. If a moderator gets swayed by idle talk in the forum, he wasn't fit to be a moderator in the first place.
Now, let's say someone publicly accuses you of cheating and all the ordinary players believe him, even though you're innocent. Even if nobody wants to play with you, you can still play almost all the games, since they are anonymous and password-free.
What other reason can the moderators give for their censorship of cheating accusations? Offensive language? I've been called much worse things than a cheater in this forum, and I've returned in kind. No damage done.
I'd love to hear other people's opinion on this. As for myself, I propose to allow cheating accusations in the forum. They will allow more freedom of speech and livelier discussions which will at least be related to actual games, instead of religion or what have you.
