actually act 2 is safe... the ledge in jehryn's house.. can't town tele through it.. but honestly I have still scammed for anni even at that spot.. just use ftele + vigor in a clever way. In truth the only safe way to trade anni is post a screenshot of it on the forums, get a MODERATOR to trade for you (you give anni to a moderator's mule, other person gives w/e they're trading to a moderator's mule, mule gives other person anni then gives you the item(s) ) or go to an IRC channel dedicated to anni trading and get a channel op to moderate a trade for you.
