Are those the trackers which demand you have accounts with other private trackers before you join or the ones which demand everyone have a >1 ratio to download anything which is impossible by definition, so everyone either gets huge seedboxes, cheats the ratio or has to download niche but big files from other sites and switch out the tracker to artificially up the ratio?

I'm sure there are actually good private trackers, but I've found there are open/effectively open (sign up only with no verification/requirements) trackers with better communities than any restricted one I've found
