JoshuaBreach, sockpuppet JoshuaBreach237, recently did the following today:

• Coldposted a low-quality SCP (no rating module, improper formatting, lack of paragraph spaces, etc.): http://www.scp-wiki.net/scp-3135
  • Excerpt: "SCP-3135 is a arthropod with a length of about 5 inches and a width of about 4 inches. SCP-3135 has 8 legs and 6 eyes. 4 of the eyes are positioned on the facial area while 2 are placed on it's head. SCP-3115 was initially discovered in [redacted] Florida on a swamp in 1972"
• Later renamed the page url to acidic-arthropod
• Created a new SCP-3135 page, which was effectively a duplicate. Deletion record here: http://www.scp-wiki.net/forum/t-5070758/deletions-48:enter-freely-and-of-your-own-free-will#post-3700189
• When called out on it, responded:
  • http://www.scp-wiki.net/forum/t-5162443/scp-3135#post-3700211 "Cause I am re attempting at it. I WILL KEEP ADDING THIS ONE WITH MORE DETAIL TILL THE ACIDIC ARTHROPOD STAYS"
  • http://www.scp-wiki.net/forum/t-5162443/scp-3135#post-3700210 "I RE DID THAT ONE!!!! THE PREVIOUS ONE WAS MY WORK"

Keep an eye on. Given this much caps lock and flailing, they're probably underage too.

ETA: got an unsolicited PM, with the subject line "I AM PISSED OFF"

I am getting so upset that every SCP I make, it gets deleted!
THIS IS REALLY GOOD!
I think half of the time they are being jerks.

Sent them the usual "the audience determines the quality of an SCP, we have high expectations, if you react this way to negative response to your work then you don't seem like a worthwhile author and the site may not be for you" reply.

And they are indeed underage. Age Record thread is up: http://05command.wikidot.com/forum/t-5167754/age-record-joshuabreach

The game idea: BASED OFF OF WHAT THE O5 COUNCIL ON THIS WIKI GIVES YOU! When you join this site, you are able to get a free PC game called: the scp foundation role play game, you are at site 19 and are given a role as a researcher or guard or class-D (depending on what 05 council gives you) and an research the many scp's in the facility. THE 05 Council will give you a security clearance card that I'm has the levels 1-5 depending on what they decide to give you. […]
