In fact I've been already using sites such as zlib, libgen... for many years. But I was looking specialized torrent trackers with more or newer content.
I've read about bitme, bitspyder, learnflakes and myanonymouse. Which one has more content? I'm looking for academic books, IT, science...

I'm not a member of bitme, bitspyder or learnflakes so I can really comment on them. I know learnflakes specialises in IT related content so you might find more stuff there that interests you. And I believe bitspyder has a lot of "certification" content like online courses that you might find useful- but zlib will have the most content in general, it might be harder to find the relevant content though (eg you might find exaclty what you were looking for except it was made for Windows 10 when you need 11) I'm on MAM and ABT and there's been a few things I couldn't find on either if them but could find on zlib.
Nothing that I haven't found on zlib that was on either ABT or MAM.
Learnflakes and MAM Is probably where I would try to get into if I were you, LF for the specialization and MAM for the community (maybe you can get what you need via request) as well as MAMs recruitment threads might help you get into other trackers that could help

The problem with ligen/zlib is that many links are dead.

@skan I've never once found a dead link - although I haven't used them much since the recent crack down over the last year or so. Are you talking about download links or the actual website url?

I mean that for many books when you try to download it... all Libgen.li, Cloudflare, Ipfs.io and Pinata links are dead.

And produce error like this

/ipfs/bafykbzacedzoyweqstesukgprv4irguywbdcwfnryjldyg2pa yzktq7txzgme: content is unavailable because it violates the Cloudflare IPFS gateway's terms of service

Does Bibliotik have more académic and technical books than z-lib?

IMO it's not a matter of whether x or y tracker has more or less content than the others. It might just happen that the one book you need is so niche, that you'll only be able to find it on a smaller tracker, because it was uploaded from someone's collection on the odd request.
My use case is to read epubs in Play Books, so sideload the Z-Lib app on my Android phone, search with the epub extension and language filters, download and load directly in Play Books (does the job to manage my reading shelf and track latest page in each). You're limited to 10 per day but can just create a secondary account. For about 9 in 10 books I need, able to source this way. Another 2 times I couldn't, I've added requests on Z-Lib (get a free account and only in the browser version, not the app) and the missing books were added next day. For the rest, the large general trackers (TL) were a better option for requests, as they have more users than the specialized learning trackers, so better chance for the request to be fulfilled on general trackers, go figure...

But on the list of trackers in your original question:
bitme - gone and buried afaik. was really good.
bitspyder - IT technical training, no robots to upload the latest, lots of packs of old content, not properly curated by mods
learnflakes - checked e-books category, mostly IT technical, same comments as for BS above
myanonymouse - the only one where I check the new uploads list daily and I always pick up a few as there's lot of both new and old content, well organised, good info, interesting uploads epub, pdf, audiobooks, mostly literature and science, less technical
abtorrents - adding this as it's a very good source for audiobooks especially series, but didn't check the rest of the content
