I don't think it is a good idea. This means more people with more money will get more votes for sub-quality material. It means that creators who work their butts off see little return because they didn't buy into the voting bots. If we continue in this vein we will be no better than Facebook. Just my two cents...
Totally with you. The thing I hate is that a lot of posts which are being boosted are not ones that would ever find popularity. Correctly as you say, it means that great posts from people who don't buy their way up will remain ignored
