"Your research stinks", "Your cooked up claims" . . . starting to sound awfully familiar.
Yes, it is quite obvious when you look at how many post against vaccines while only one usually is posting in favor of them that the votes are the work of multiple IDs belonging to the same person. I have no doubts that it is the same person that feels compelled to return to the scene of his former crimes and commit them over and over again.
Although his ID numbers have been trimmed a bit of late, I likewise have no doubt that he will create more. It appears to be a never-ending farce. Ultimately, he also will be unable to help deteriorating into name calling and slurs and will again have even more of his IDs trimmed (and in turn create more to keep misbehaving and voting with).
In my opinion it is the behavior of an ill adjusted anti-social misfit - quite possibly an immature brat who needs to offset his failures in real life by creating a cyber identity he uses to sew chaos, demonstrate his false sense of superiority he uses to mask his feelings of inferiority and attack anyone who dares disagree with name calling. slurs and put-downs.
