[NEED] Youtube Comment Upvote bot

I am looking for a tool that at least has the capability of upvoting a comment I put in it for upvoting (commenting is a plus).

Thinking of a bot where I input several youtube accounts and have them each with their respective channels upvote a specific comment.

I know these exist here on the forum, I just cannot find it right now. Preferbly free(?) as I thought I saw a thread about it some time ago. Anyone knows of such a tool?
