Found deleted Roundabouts in the Area i was mapping exclusively for the last weeks. After i put them in again i found more bogus edits tonight. Foot/Cycle/Waterways which are definitly not there. Footways without any connection although i know there is one etc.

The user seems to just map from memory and using potlatch. He is not really carful doing edits and i already tidied up a bit by deleting points and ways without any tags and connections etc.

Now i'd like to contact that user but there seem to not be any standard way to map a username to an e-mail address
