I always figured the point of an ignore list is to get certain posters off your back. Some just rep you for no reason or they start shit in every thread they can and it gets really old. I don't really care about the reps, but the constant thread to thread stalking is childish. Posters I have put on the list still can quote me and start shit anyways. My "suggestion" is that they shouldn't be able to quote or see you AT ALL. What's the point of the list really, it doesn't make a difference.
Then its stupid altogether. And reporting does no good on here.
I'm fairly sure everything that's reported is handled. There's no way to see what kind of infraction is given to a particular user when you report them, that's just visible to them and staff. But just because you can't see it doesn't mean they ignored it.
