most of your retweets is from accounts with couple followers. probably coming from trafic exchange (like addmefast).
no bad fillings, but i think that this retweet is not worth, because retweets from bots mean nothing
Please don't spam my thread with useless and false comments like yours, just to making up your signature posts, so such posts should be reported to moderators and to signature manager because you are just spammer.
The users could be checked and all of them have tweets and followers so couldn't simply being bots as you noticed just to bump your signature posts. Shameful behavior really.
