Next time, mention it to the dealer. If addressed by a player, the dealer or room manager has to rule. If they chose to permit sign language at the table, then I would have collected my chips and left the table. You are right, sign language is no different than speaking a foreign language at the table, imo.
I suspected a deaf man and his neighbor of collusion at a table I was playing at. I watched for awhile and detected what I felt were 2 signals, they were doing squeeze plays. I finally got up and informed the poker room mgr and they thanked me profusely. Apparently 3 dealers had already mentioned they felt the players were colluding and I was the only player to mention something. Apparently they have some stupid rule about collusion, players have to report it, not just dealers. So since I spoke up they asked me to write a report on my observations, (I did after I was done playing though) and security reviewed the tapes in conjunction with my written report and the players were then banned from our casino's poker room. (After my initial conversation they were moved to different tables so they couldn't sit together).
Anyways, if you suspect, say something, if you don't feel comfortable saying something while the players are at the table then get up and report it to the floor. And for the record, there is no reason to make a heart symbol while in the hand - they were cheating.
