Cryx88, blocked for Copyvio, had a history of editing on Reformed and Presbyterian denominations, and creating articles on tiny, sometimes non-notable ones. You can see the many speedy deletions at his talk page. Cryx88 was blocked on 6 March, and his talk page rights were taken on 9 March. Calvingabor showed up on 10 March and immediately began editing Reformed and Presbyterian denominations. You can see speedy deletions similar to Cryx88 at his talk page. What makes me certain is that Cryx88 had a habit of removing a particular section of text from Calvinism, usually with no explanation ([1], [2], [3], [4], [5]). On 2 August and 11 August, Calvingabor made the same edit, with no explanation ([6] and [7]). JFH (talk) 18:46, 2 August 2014 (UTC)
I've also noticed Cryx88 was the creator and prime contributor to ((US Presbyterian and Reformed denominations)). In February the template was redirected to ((US Presbyterian-Reformed denominations)). For some reason Calvingabor blanked ((US Presbyterian and Reformed denominations)) in April and then started ((Presbyterian and Reformed denominations in the United States)), to which he has made many contributions since. --JFH (talk) 19:32, 4 August 2014 (UTC)
I'm adding Johnfarel because his first edit was to undo my revert of Calvingabor removing the Pew Forum text from "Calvinism" earlier that day. --JFH (talk) 20:34, 11 August 2014 (UTC)

Clerk note: Jfhutson, nice report. I indeffed and tagged Calvingabor based on duck. I tagged the already-blocked master. However, I'm not comfortable blocking Johnfarel based on only two edits. I realize that the first edit removed the same material the other two accounts removed, but it did it with an edit summary, and it's still not enough without something more. Also, the timing isn't as obvious as the other two. I don't believe it's even enough to endorse a CU to see if there is a technical relationship between Johnfarel and the Calvingabor (the master is stale), although I thought about it.--Bbb23 (talk) 22:19, 12 August 2014 (UTC)
This user showed up during the last SPI, and I stated then why I suspected him. As soon as the first sock was blocked this one started editing pages which have been heavily edited and/or created by Cryx88 and his first sock. JFH (talk) 19:25, 15 August 2014 (UTC)
Some additional notes:

Clerk note: Now that we have more edits to work with, Jfhutson, I need actual diffs between Johnfarel and either the master or Calvingabor. Showing the intersection of the articles and even the areas of the articles in which they edit is insufficient unless their edits are similar. Not using edit summaries is common and has virtually no evidentiary value.--Bbb23 (talk) 00:55, 25 August 2014 (UTC)
I'd put this at about 95% certain to be socks of each other and of Cryx88, although correlation with editing is important. (Sorry Bbb23, didn't realise you were reviewing this as I was doing the checks.) Risker (talk) 01:05, 25 August 2014 (UTC)

Clerk endorsed. Although I'm probably willing to block based on duck, I think there's barely enough time to do a CU before the data is stale. I'd like both confirmation and a more recent CU for the future.--Bbb23 (talk) 19:04, 9 November 2014 (UTC)

Common to his socks, works on Presbyterian Church articles and adds copyvio content with source [12][13]. Registered two days after last sock blocked. Other, overwhelming bit of evidence available upon email request, but this should be enough. I'll leave it to others to block. Anna Frodesiak (talk) 19:04, 10 August 2015 (UTC)

Confirmed: PresPCA (talk · contribs)=Guido de Brés (talk · contribs)=Cryx88 (talk · contribs). Blocked and tagged -- Euryalus (talk) 09:03, 7 November 2015 (UTC)
I blocked Debeza12 as an obvious sock for obvious reasons (email if you don't see it) on 09:35, 20 November 2015 and then Illones01 registered 09:45, 21 November 2015 adding sourced copyvio content to Presbyterian articles, normal MO. addition, source.
Debeza12 already blocked but not Illones01. Seek CU for sleepers as it is now Dec 1 and his new incarnation is likely in use.
