I did an experiment to see if their reliable.
I joined their community and proceeded to write BS on the pages. I wrote that Sentry, Gladiator are rip offs. I gave wrong information, deleted parts of characters pages. Gave characters new power sets, spammed the pages with random stuff, also wrote a bunch of stuff saying DC was better. There is a person on their who is like the moderators on CV. He deleted anything bias, wrong, stupid,etc and added all the stuff I deleted in a manner of about 10 minutes. He then messaged me and said if I don't like a a character, like a company better than the other that that was fine and that I was entitled to my opinion but that people come here for information not opinion based stuff. He then blocked me and banned me from writing anything at all on Marvel Wiki.
I therefore conclude that Marvel Wiki is a reliable source and that anything unreliable is dealt with and fixed in a manner of minutes.
I will do DC wiki next.
Any questions or thoughts?
