> Look at the people self-voting close to 100%, do you think that behavior is beneficial to you, themselves, me and others?

I don't know. It depends on the content. A content creator who produces useful content and upvotes it, but does not spend time reading others' content or generally curating is still a valuable contributor despite 100% self-voting. A spammer who self-upvotes and also votes on others (or perhaps a pair of spammers who vote on each others' spam but not their own) is still an abusive spammer. The statistics in your post by themselves are useless, as is the implication that 'self-voting' or a high self-voting percentage is inherently harmful or evidence of abuse. Neither is correct.
