Yes, unfortunately it needs to keep track of deposits from each user, and then they transfer to their chosen recipient with no fee whenever they like. So it generates addresses for them for each coin. The idea is that they can direct faucet/PTC site earnings direct there, then use them to support projects. But they can cheat and just send in coins from anywhere!

But having to run a node for each coin means I wont be able to support so many coins now.
