Some tips that could help you.
1.) Hide My Ass Ip's are pretty much blacklisted and can get flagged down fast
2.) If you buy accounts, try to find aged ones. (pretty hard to find though)
3.) Flag people if they steal your video but please do not flag competition just because you don't see your video ranking better
These flaggers have been pissing me off lately. I can't seem to keep a new video up for longer than 2 weeks... thank god I have some aged video that bring me my autopilot money.
I heard this a lot of times, but i hear more times to boost video after upload
