No. Twitter accounts are not verified in any way, and can be 100% false, not requiring any name at all.I don't have first hand knowledge either so we're in the same category.
I may be wrong since I do not use Twitter but does it not require one to register with their full name and other basic personal information? I think that alone makes things slightly more official and credible than things posted on this site where I can use an name that I want without fear of anyone tracking me, other than the site administrator.
There are, in a few cases, Twitter verified accounts, that are used for celebrities and public figures, but certainly not for the masses.
Your post is kind of ironic, with you just indicating that 99% of posts here are garbage. You are certainly a contributor to that with your last couple of posts.
