there are a lot of crazy people on here, just mirror of reality. why not just block them? that is why it's there.

first you have to say who did it and what they did, those are the forum rules

I agree with philidor's position (snkr).  I once reported a member who had a porn photo for his icon.  I asked him nicely to remove the photo to no avail; the tech support contacted him and asked him to remove it; finally the bossman disabled his account.

There is no need to put up with abusive people on this otherwise family-friendly website.  Report 'em, says I.

Yours in Christ,
