There's a username in an enwiki cohort I pasted in to Wikimetrics that seems to be a normal one, but Wikimetrics checks it and indicates it is invalid: Ccngodoy See, for example: https://en.wikipedia.org/wiki/Special:Contributions/Ccngodoy I'm not sure why this username is not being considered valid by Wikimetrics.
Other usernames that I can't validate and don't know why: Dd-556 Finding Zeno
Also: Hansenr11
These usernames are invalid whether pasted in or uploaded via CSV.
The labs db data has issues around September 20th, part of the data for this user is missing. This is by no means a common event as we have not seen this happening before. We will work with our DBA and update this bug.
