Our listserv is being invaded by a guy who is subscribing the list to dozens of commerical emails as a prank. We know who he is and have tried getting law enforcement on this. One solution we have tried is to filter whole domains at a time. However we are now at 10 lines of Filter= and we wondered... in the NEW listserv (full version) is there any way to increase the whole filter to more than 10 lines? Is this something to place in a wishlist for future versions? Also we wanted to filter out something else. We went to http://www.liszt.com and would love to filter out ALL of those. It seems that a person with netscape can change their own email address to that of the listserv and subscribe OUR list to other lists and vice versa. That has become the problem lately. Is the software programmer here? Is there any way to deal with this globally from our headers? Is there a way we can globally keep creeps like that doing this again? To date he has done this 56 times and our subscribers are getting VERY upset. Thanks for any ideas. (Yes we HAVE filtered HIS real email address out already but it does not help when he changes his email address in netscape to our listserv one and subscribes us to all this junk.)
