I don't know for sure, as I don't tweet, but it seems to me that the confusion comes from the period. "Pervasip Corp. Retweeted".. I read that as 'originally posted by Pervasip Corp.(PERIOD) and Retweeted by this poster' as opposed to 'Retweeted by Pervasip Corp.' Meaning PVSP isn't retweeting. The individual posters are retweeting PVSP's original - which is a good thing.
