Okay, you don't like "incessantly". Replace the word with whatever you like man, it's all good. 12 tweets in the last couple of months is plenty enough though - without being incessant of course.
It's not just the number of tweets but the content too. The fans don't want to hear about his latest hairstyle or how many kickups he can do when the team is reeling from another defeat. Maybe if he tweeted that his performance was unacceptable, and was a contributing factor in said defeat, the fans wouldn't mind so much.
