So there were a couple wikipedia accounts that were active 24/7. (1) They were propaganda accounts for governments. What they did was, they had a person on Wikipedia 24/7 who would edit things to be pro-country of origin. Multiple people took shifts to accomplish this. I think it is significantly more probable that Shila is simply a collective of users who have nothing better to do than shitpost on DART.
As to why she never responded to messages, it took me days of searching on my mobile phone layout to find where the friend request and messaging options are. So if we assume these people are like me and are taking shifts mostly on their mobile phones, it makes sense how they couldn't have found it. The mobile layout is clunky and I am thankful it is getting fixed.
BUT, this doesn't mean that skynet and such do not exist. I personally believe one user on here is a bot, but I am not sure. And, no, it isn't Oromagi.
I mean, after all Best.Korea I am pretty sure is a North Korean propagandist who is actually working for the North Korean government.
So if North Korea cared enough to join, then why wouldn't other countries?
