Yeah we tend to ignore Sidewinder and Mechaforce as much as possible
They do do a lot for the community, their movies have been a large chunk of the cinema for a long time and they have various plugins. Depite their complete lack of tact and coming across as abusive they don't tend to pick on specific people.
The rigging of the cinema has been a long running topic and we have a different system with the Gold users now which cuts down on people setting up false accounts to vote.
One thing you have to consider before you take low votes personally is that different people use different criteria to vote and in a lot of ways you're movies may not be worth a higher vote no matter how much effort they took. Some people may even vote only 0s and 5s in order to make the most difference with their one vote. I notice you vote highly for everyone, maybe voting above or below 3 if you think its good or bad. Personally I use the full range of 0-5. I only give out 0s to stuff that is completely worthless (I think only 1) but then my 1-5 is a rating of goodness so a 1 is not that bad.
Also some people have made very professional looking movies with a story and everything. Some movies at least must be rated lower.
Rather than complaining about abuse, why not try ignoring that and consider why people may have voted lower or just use any constructive critisism you may have got? After all if everyone just pats each other on the back for every movie then no one will improve and that is what most people are here for.
