I don't understand this thought process I'm seeing from some of the users here. First they claim this place is a great environment to express themselves and its so inclusive. Then the site experiences this sort of action with accounts being purged and whatnot and now the site is "terrible" and "the worst thing ever made" or my favorite, the site "was never good to begin with." I know tumblr is not a hive mind, but the people saying this sound like real dumbasses when they've been using the site for years and then make a heel-face turn based off of one situation.
The next idea is to flood twitter. Aren't you guys kicking the can down the road with this sort of logic? If twitter decides to do the same sort of purge where exactly are you going to go then? As current consensus is shows Twitter is no better with censorship and shadow banning people with 'ad-unfriendly' content. How exactly is this any better?
Please think long term rather than impulse decision making. This 'purge' or change is not the end of the world. Please diversify where you have your audience if you take nothing else from this sort of thing just realize nothing lasts forever and things change whether it benefits you or not.
