uuid 028b6b8dce6241c60c313f9a4dd1ee0c957db7e5 suddenly has numerous ids from very different people merged into that uuid.
This makes user data entirely unreliable by displaying random names and merging contributions of random persons.
I tried to give this a quick investigation but no idea what's going on - Git change 77873dc9f778443df352013bcd77a80aaa4d45c6 somehow "renamed" uuid 136155e528cf630d61a8352ab1a80ae2ddbc7a03 into the new uuid 028b6b8dce6241c60c313f9a4dd1ee0c957db7e5 (which was previously one id under 136155e528cf630d61a8352ab1a80ae2ddbc7a03). Beforehand, git change 7b7d06d6a57e69f1cb855fee5673b66180cc4635 changed the uuid 00da234ef9520f36d14af411cda0755be9d6d529 into aff499e52b8bcd8e3357c7dea8e77d1a7be28f30.
(It also removed data for reasons I don't know, e.g. the email address value of id 00293d7819ecddd16fd561bca66c42e59213b532 ).
I checked the diff of the last human git commit d27b36e73df818b156e45c11950efd4fd2ebe151 by myself but I don't see that account touched in there...
