A blocked editor created a new account
The thread's summary was edited.
After https://translatewiki.net/wiki/Special:Contributions/188.32.0.0/16 was blocked here, he started making translation requests on Meta-wiki (https://meta.wikimedia.org/w/index.php?title=User_talk:Kaganer&diff=prev&oldid=17855311), and also using an IP 77.37.135.11 (https://meta.wikimedia.org/w/index.php?title=User_talk:Kaganer&diff=next&oldid=17896984).
Now per https://meta.wikimedia.org/w/index.php?title=User_talk:Metalhead64&diff=prev&oldid=17923834 I'm sure Headwikisponge12 user account belongs to the same vandal and you may want to block it.
Hmm, looks like that account was never created.
But now he is using User:Happy13241 (his message on dewiki).
Stryn, not read new comment. Other admin unblocking https://translatewiki.net/wiki/Special:Unblock/188.32.0.0/16.
