Which helps illustrate: we need your (plural) co-operation in reporting rules violations when you see them. We can’t be everywhere. It’s frankly frustrating for us to find the complaint that, “I got warned for such-and-such but So-and-so did the same thing three months ago and didn’t get warned.” It typically means that we didn’t see that prior offense.
(Sorry, slight hijack, but we do have new members reading here, and it doesn’t hurt to emphasize – even for long-time members – the importance of helping us enforce the rules.)
