That blue mark will also be misused by troll farms in Russia for instance to give some credibility to the account. And of course for propaganda of political parties.If you want a fancy blue check mark your going to have to pay for it. don't see an issue there. If people are so desperate to have a blue check mark and have their twitter audiance retweet them that they will throw a temper tantrum like a child then they can part with $8 to continue feeling important.
