They shouldn't do any damage if they have enough organic matter to eat, but a lot of potting soil is low on organic matter, and they may go after the roots if they get overcrowded. If you get too many worms they may start to leave the pot to search for greener pastures as they would do outside. I'm afraid the Yuck factor would get to me personally and I'd have to replace the soil. Interesting topic and wondering what other peoples opinions are. Apparently some people do put them in their pots.
