Hopefully addresses in our profiles will be logged at some point as that seems like the perfect place to put them or have a history of addresses used there for easy access if you need to prove you own one. You also don't need to post one in off-topic but just use them naturally. You can also send them in a PM to default trust as they won't be deleted then.
It's actually DefaultTrust you need to send a PM to. (Not trying to be pedantic, just thought someone may do this after reading the thread).
