Especially if one only lists freemail addresses on the list (like we are going to do for now), the worry it pretty small. Why would the 419/phishers want to spend time blocking normal peoples freemails? And if the spamtraps are well hidden (or process otherwise manual), it would take serious effort to get someone listed.
