How would this open you up to abuse? Having a community with the same name as your username auto created where only you can post new threads wouldn’t open you up to abuse. But it would greatly benefit interoperability throughout the fediverse. Lemmy is currently the least interoperable fediverse software while also being the second most used. I also think its the most valuable since up/down voting and threaded replies makes the most valuable information the easiest to come by and follow. So it would be great for the best fediverse software to also be better at playing nice with the rest of the fediverse
