It has been a long time since i checked their Twitter, it has been a lot of days since they posted something about the project.
I hope it's not like what they twitting till now. I am referring to future partners related tweets. Let's see if something interesting or not.
Their Facebook and telegram are active enough! I'm not that interested in Twitter since I got my account banned by trying to increase more followers within a day. You can ask that in their telegram group. There are many of active admins.
Also, Recently I've seen many of fast follower increasing accounts are subjected to ban temporary or permanent. Since more and more community is gathering around Tachain, That might be also can happen.
I am always saying that telegram is good source to ask your questions/queries about project. But as per my thought twitter also mandatory because lot of the people are visiting to the twitter first to know more details about project.
