I too often get multiple reseed requests. I just checked my inbox an I have over 7 cases in the past week, and and 5 of those are within a minute (one had 4 requests in a minute (Hans Berlin dominates and fucks Steven Ponce! I uploaded 15% of the file to this request) - User is brand new, zero seed points and no ratio. OK, doesn't understand how this works. I'm not as upset about that as reseed requests that they don't seem to want to leech.
I get a reseed request, look at the torrent and see zero leachers (often within 30 minutes of the request). If you want me to upload, you'd better be ready to download.
Then there is the guy who has PMs turned off (he has 17 TB DL so not a newbie) who every month asks for Sean Cody SC-005 and SC-011 that are available in other SC collections (occasionally Free Leach but these are small files).
Occasionally (if the requestor has under 100 seed bonus (I should probably cash in 10K, my ratio isn't great from ISP blocking stuff a decade ago but I have a huge buffer in the TerraBytes) I'll move the file into my shared files and a few day later someone latches on and I'm uploading the file. But most of the time I'm wasting effort putting this file into my forced seed queue. A reseed is requested but for the next week I never see anyone leeching.
There are a few folks that if they ask for a reseed I know are good (like moderator MrMazda, zwinnia). If the seed bonus is over 1000 I will make the effort.
I'd say 50% of the multiple requests I see are all within a minute. Fumble fingers or new.
