Today Twitter has been removing tweets from all crypto related channels. My Channel went from 1500 tweets to 20 tweets today and many other crpyto channels have had all their tweets removed. What does this mean for Bounty campaigns that send out stakes for tweeting? All my hard work of re-tweeting and tweeting is gone... 
This is some kind of failure or error. Twitter is used by all exchanges, miners and all current ICO. Try and ask twitter directly as to why your tweets are gone and you probably can still get them back if you know for certain you have not violated any of their terms of use. The reason why they got deleted is that you have violated some of those. There must be official news.
