Don't have a premium, so people demanding that it be 'official' critiques ignore normal comments. And I participated in a crit-giving contest. Gave 10-15 of them. Got 2 in return.
Or I give a critique on a story/OC profile and people blow up, screaming that I'm hating on them when I do my best to point out what is good, what needs improved, and some helpful sources both backing up my claims and helping with suggestions.
