Blocking TF alone is not enough... but there is not much more one can do (at least that I know of at the moment).
Sure, there may be other problems! I am not at the FT server end so I really can't tell. However, I do know that some ISPs have blocked some TF services but I don't know enough to elaberate. Some of the TF adds lead to one becoming locked out of getting back to the original webpage, so some ISPs have had this reported and there is now some traffic blocking going on.
I would spend more time tryinig to solve the problem but it seems the people at FT just get more upset with me when I try to help so I am bowing out. This will be my final post on FT unless they decide I am actually helping.
