If you're going to bother with accounts it's a bit annoying that you can't just contribute directly from your account. Having to create a pull request is slightly annoying.

And at this point my personal list of uBlock rules is tailored to satisfy some very specific personal needs which I'd feel a bit apprehensive about just sharing without some degree of anonymity. Heck there are rules that would allow you to identify my account on other social media.

Also if this is to get as popular as userscripts/styles are/were then some way of finding rules per webpage would be nice.
