cometaurora (who has gone by at least two other names since 2017) recently posted on someone's draft thread: http://www.scp-wiki.net/forum/t-8099079/this-is-my-scp-critique-as-harsh-as-you-would-like#post-4027879
Chameleons can't change colour like that, gotta throw the whole SCP away now.
This is admittedly not the first time they've left problematic feedback, though the first instance was in 2017: http://www.scp-wiki.net/forum/t-2243002/the-anomaly-that-s-me#post-2800002
Just a small recommendation, don't use "SCP-2571" as it may be taken before you finish, use "SCP-XXXX" instead as a place holder.
As well as more recently, some whining/vehemence: http://www.scp-wiki.net/forum/t-7787827/the-ball-mouse-scp-xxxx-need-critique#post-4013438

1. My comment was a joke
2. I don't ever see a single person in the IRC Chatrooms.
even when i register it says no one is there
Of note, they also told a wikidot developer "I don't understand your broken english" http://community.wikidot.com/forum/t-7884496/hundreds-of-features-missing-please-help#post-4019277 and were addressed for it.
Keep an eye on.
