Adding this tracker (and crawler!) finally results into downloads from me: http://tracker.insulaocculta.i2p/a
I'm happy. Use me. I have ~1PT online and my hardware is old. Can't invest because prices go up because of this AI (which noone really needs?).
Issue: I can't inject this tracker via "Config -> I2P -> I2P Tracker -> Sync Now" Injection-thing into torrents having a lock-symbol next to it. Result in tons of work for my fingers. Please do not say it does not do never nothing. It does for normal torrents. So it would be for I2P torrents I guess because: why did I get them first :-)
