According to minnowbooster tos:
What constitutes abuse of @minnowbooster?
Using multiple accounts to post duplicate content and purchasing MB upvotes for all of them.
Upvoting posts with MB that are written in a copy / paste style.
[Edit] Using a MB vote for very short or repetitive content. Length is subjective, but 150 words is a good safe guideline, however original art, photography, video and animations will be exempt from the 150 word guideline.
