1) Fake solves
2) Lying about your times
3) Making videos people find useless or uninteresting
4) Making threads about these things mentioned above
I would suggest taking more time to make your videos, provide scrambles (for cubing videos) and be truthful. To be honest, by asking why everyone rates your videos 1 star you are only asking for trouble...
Simple, post avg of 5/12 vids relatively regularly that are decent considering your PBs/general averages. At least, that's what I do o.0
Also, don't make any unnecessary vids whatsoever.
