Seems a lot less obnoxious than the ads they used to run (don't know what they run nowadays). Bit sad that JS is too limited to be a miner that can't be implemented more efficiently in something like X86 (randomX) or an ASIC (BTC), I imagine it would have caught on otherwise.
You could use WASM and WebGPU now so maybe it will make a resurgence.
It's pretty much dead. Nobody publishes quality stuff there anymore.
kickass torrents used to be my go to before it got taken down. TPB used to be better, and it has gone downhill for a while.
