Three questions of mine were downvoted about 10 minutes ago during a 1-minute interval, and there have been 5 serial down votes on my questions in the last 2 days. Apparently this might be carried out by a single user, and could mods take a look into this? Thanks in advance.

I suspect that this user might be a "prolific" one that has been answering a considerable quantity of low quality questions, since my daily routine here is to filter out LQ questions simply by using question-status-only-related conditions.

If my conjecture is true, I hope that my loss, which has not been corrected by the automatic system, could be recovered.

@Ѕᴀᴀᴅ Keep in mind that (1) we cannot see individual votes and (2) most serial voting is automatically reversed after a day or two.

There is really very little that we can do about this.

@XanderHenderson I do understand the circumstance, and most double serial votes are ignored by me. But it's just that from time to time some users really cross the line, yet the automatic system fail to act. (Sigh)

@Ѕᴀᴀᴅ I agree. It is annoying. But it is very hard to do anything about.

(Ahh, buggy network)

@Ѕᴀᴀᴅ Unfortunately users involved in this room (or moderation in general) are often subject to such attacks. I've lost count of the number of times this has happened to me, e.g. currently there is a disgruntled user who frequently donwvotes my answer then upvotes all the other answers - all within a minutes time.

As another example, I have had 6 downvotes yesterday and 4 today. Most of them have been reversed.

@Ѕᴀᴀᴅ Oops, above, by "this room" I meant the CURED chat room
