Alrighty, I'm posting the evidence below for everybody to see.

I initially noticed , who had a disruptive username. His first action within 60 seconds of creating his account was to create a userpage consisting solely of "heil masem", an attack on . Since his later edits, including signing up for the WikiCup with the al-Qaeda flag, demonstrated that he was here to troll, I blocked him indefinitely. Enter , who, within two minutes of creating his account, is able to perform an intricate template time update on a nomination by . Note the interest in Wikipedia:Featured pictures shared by all three accounts. Nick then posts to Masem's talkpage, linking this vandalized version of Wikipedia:Sockpuppet investigations/Wagner and identifying Pirated as a sock of Wagner. In that vandalized revision, note that the vandalism included references to Montenegro. Pirated, after being reverted for attempting to use the al-Qaeda flag, requested to use the Podgorica flag. Podgorica is the capital of Montenegro. At this point, H.W.C. complained that I am "blocking users with little evidence and expecting people to clean up the rest after him again" (emphasis mine). Note the use of "again", when I have never interacted with him under that account before.

Additionally, note that H.W.C. created his account and immediately started making featured picture nominations centering around video games. Wagner has occasionally talked about being a video gamer to his own socks. Additionally, H.W.C. signed up for the WikiCup with a Montenegro flag, which he later changed to the Podgorica flag. He clones 's userbox and adds another of Mason's userboxes to his userpage. Mason Doering is a known sock of Wagner.

Nick's modifications to the template were on a nomination created by H.W.C. On Wikipedia:Featured picture candidates/File:Poolside 03.jpg, H.W.C. showed up in twenty minutes to comment on Pirated's nomination. H.W.C., Mason Doering, and Pirated use similar edit summary styles.

Finally, checkuser identified that H.W.C. also had the account . Thanks.
