After some tests it seems that I actually have an upload issue. I've tested my download at 876 Mb/s, but my upload is stuck at 0.2 Mb/s
At the beginning of the week I did not have this trouble: I remember having freeleeched a torrent and uploaded more than 40 gigabytes within a few hours.

After 2,5 hours of freeleech, I have 31 leechers, who are at ~ 22 % completion; thus I'll continue to seed until everyone reaches 100 %…
(And I have now to solve my upload enigma.)

I concur with the observations above: sine 1~2 days most torrents are in trouble…

@mihaig110 Same thing happened to me exactly 8 days ago. The takedown was so swift (maybe 1 or 2 minutes) that no user got enough time to even attempt a connection!
As usual my torrent (2 vids) had thumbnails, description & screenshots, which usually gets through with no problem…

During the 80 minutes preceding that very takedown, I had two more (older) torrents also DMCAed!
(Three unrelated torrents deleted in that short interval of time !!!)

No, I definitely have a real trouble; at the beginning of the week my upload would reach 200 Mbps at moments.
I'll keep investigate. Maybe a damaged optical-fiber cable?
Thanks for taking the time to read and answer me.

@lololulu19 I'm no technician at all but, according to Wikipedia, .jfi/.jfif seems to be a slight variant of .jpg: the algorithm used to compress the image is the same but extra info is store differently (as far as I could understand).
As for other file formats I have also experienced positively the upload on gaytor.rent of files with extension .heic (which is Apple renaming for .heif).

While JPEG algorithm is lossy, .heif can be set to encode losslessly, as for .png (while producing smaller files than .png).
Also, .png has a nice advantage over the former formats: it can preserve transparency. A feature which is however useless on gaytor.rent since every uploaded image is automatically converted to .jpg (and transparency → white…).

Quite strangely, the day after my first message, my upload speed came back to normal (~ 500 Mb/s) and remained such till today.

I've waited 3 days before experimenting to freeleech anything; I chose to freeleech a rather small torrent today.
At the very moment I did that, my upload speed fell again at <1Mb/s!!! (I've checked on www.speedtest.net and some other similar sites.)

I'm left with two hypotheses:
— my ISP is delivering an instable upload trafic when I freeleech something (3rd time in a row…);
— there's an obscure unexpected interaction between gaytor.rent & my fiber box (the speed of transfers between the computer and the box, using FTP, doesn't seem to be affected)… 🤯

I've freeleched a torrent about 1 hour ago, for which I'm the only seeder. There are currently 12 leechers trying to grab, it but my upload speed has just fallen to ~zero!

Quite oddly the same phenomenon occurred two days ago when I freeleeched another torrent for which I was also the only seeder. I then tried many things, such as rebooting my internet box, even my computer. Nothing helped…

I will add that my upload speed is zero whichever client I use; see the two window captures (one from Transmission, the other from BitTorrent):

Does anyone has some clue to solve this very new issue? (at least to me…)

@jjazz44 Eight months ago I installed NordVPN and it totally blocked my torrenting client Transmission. I wrote to them and got a quick answer saying that they don't implement port-forwarding “for security reasons” but that they seriously think about it for the future…
I then asked for a refund, which I obtained some days later.

@john32123666 You wrote: “It should only works if both torrent has a seeder.”
Actually the rules say otherwise.

It is enough that the original torrent has seeders; which was the case.
As a matter of fact, some hours after this conversation the duplicate was removed (thanks to MrMazda).

@drekkin I'm not that stressed at all…
It's just that this reporting precisely (though renewed several times) has no effect; while I've done some others more recently, which were all taken into account.
I was rather curious to know what is special about this peculiar one. But I agree with you: it's a minor matter.
