For me, I always do a little research before join project. Account who post it, is it official or not. Statistic of that account. Found something weird or not on their business (including rules, roadmap, schedule, their social media channel and its popularity). And I always put myself netral first, the more I found promising statements on a project, the more a doubt it till a deeper research makes me sure. Well yes, I'm new member too. But, I have been a BTT reader since 2 years ago.
