harassment

If i start getting harassment from a other forum but not a forumotion forum, but it is phpbb is there anything i can do about it. I.e there members coming on and saying stuff on my board that are not true, as in slander about me or other members of my staff ??

Ban them. Warn them.

Yes i could do this but they could still get on, or send other members. It all to do with the forums founder who is not happy that we lefted her site (Long story but big misconduct going on there) and made our own, and they have been going around telling people lies and will prob try and get onto the board, and post stuff on there which we dont want our members too see.

I was thinking more of the lines phpbb warn them or something like that.

make a different site or change address.

I am not changing site or change address, as we have 297 members and we don't want them being confused by wat going on

Okay I am sorry I do not know what to do then sorry.
