This address is used for Urunit signature campaign at some point, and as you can see there is Urunit token transaction to this address, to be more specific, 21,862 tokens in this transaction https://etherscan.io/tx/0xe6b2fdf8939dafc67ad41d53976c1f26973181cdaf740b4a72eb621380ede17e.
According to spreadsheet https://docs.google.com/spreadsheets/d/1ypn_mnMqZ8hhOD4Z6BRLvKKwdXJYzpx556cCG7s8U6s/edit#gid=1572635615, this address should have received 10833 tokens:
So, numbers don't match, 11029 tokens are missing
Yet again, someone claimed twitter bounty using the same address (https://docs.google.com/spreadsheets/d/1ypn_mnMqZ8hhOD4Z6BRLvKKwdXJYzpx556cCG7s8U6s/edit#gid=1227577233):

EDIT
I have found another alt account, but this is becoming interesting, apparently newbie account Zykexia joined Covex signature bounty but in spreadsheet it clearly says Junior member rank (https://docs.google.com/spreadsheets/d/1YofTv0GNCidMdKHXxe1X_gobEwgakiuD5mKormzPSZI/edit?ts=5b5f9083#gid=1843670526 archived http://archive.is/Z3NAC). It was few months after merit system was introduced so account should be newbie because it has 0 merits, but that's OK because bounty was managed by...wait for it...bounty manager Arshe26.
2557 token transaction to Arche26's address https://etherscan.io/tx/0x040e99a775ae7034879a831854a17a01d62320364ad49580e311a8c54eb1b134 matches numbers from spreadsheet:
EDIT 2
Now, why would that be all, account Zykexia used this twitter account several times:
Facebook user URL: https://www.facebook.com/rheamae.dayandayan
The same twitter was used by account...you will never guess this...
Twitter Profile Link = https://twitter.com/flyingmachine36
Account FlyingMachine360 used this twitter here, here and here as well.
