Cait's issue in the removing ticker links thread HERE.
She was asked to remove her egg, and now she is IMO being a bit picky because people have tickers that are allowable because they are not linked-back.
IMO we here don't have to worry about other sites TOS...we worry about ours. Each member is resp for their sig orign and if that site wants to come at them because they are not linking back that's between that site, and that member. Just my .02 tho.
