# Is there a danger of up-voting someone too much?

Every now and then, I recognise someone I know on this site who I didn't notice earlier. Unbeknownst to them, I go through their questions/answers (expecting they will be of above-average interest to me) and might up-vote a whole lot of them.

Question: The system has been set up to detect mass down-voting of a user's questions/answers (and the down-votes may be undone). Does a similar thing happen for up-voting?

Although the system might revoke these, I always encourage you to upvote good answers and questions. When the system undoes voting, it does so without any moderator interaction (moderators are essentially blind to who voted on what question, always). But vote vote vote! –  mixedmath Dec 22 '12 at 2:24
Oh wow! I am not the only one who behaves in this manner! Since there's already been an accepted answer, I suggest that you avoid going hog wild. 10 up votes in an hour for one user is definitely the sort of thing that would trip a flag, as described below. I usually amble around a bit, look at the user's SE-wide activity, and only up vote what I can understand (with confidence) and find worthy. I've never had a problem with being flagged for serial up votes on such occasions. –  Ellie Kesselman Jan 1 '13 at 12:09

Yes. Mass up-voting of a particular user's question/answer by another user also gets revoked automatically. (I did the same to a user sometime back. I think I up-voted around $10$ of his/her answer within a period of an hour. It got revoked within a day.)
