What happened to that account, s/he started giving inaccurate and sometimes conflicting information, I tried to correct one of that information but he blocked me.

At least it's better than before.
It seems that @Bitcoin is owned by someone unkown who's leasing out that account to the highest bidder. The highest bidder used to be Roger Ver, hence the BCash propaganda posts, but now it's controlled by a true Bitcoiner with a dislike towards everything Roger Ver was Tweeting about.
The downside to this is that we don't know what will happen when the person who's currently in control of the @Bitcoin account no longer has the funds to extend the lease. In that case I'm pretty certain that Roger will attempt to get it back to shill BCash crap again. It really sucks that the actual account owner only cares about profiteering and not about the community that Roger has been lying to for so long.
This is the current account lessee;
