I think I know who this is! I mean. It’s all right to up vote yourself from time to time. It’s your investment and things aren’t black and white. If i guessed right who this is it would mean that hes not voting much for anything else. In that case I wouldn’t see that as an abuse, rather as a bad investors choices and i would understand that that the community would want to shut him down. Maybe try to discuss with him first and flag only if he doesn’t listen to reason? That is my opinion:)
