Last night while updating my system, I noticed that a random aur package my system depends on was orphaned in the aur. It's some random deep-down dependency of another AUR package, and it's not received any upstream commits in a while. Nice and stable, just needed an owner. I decided to adopt the package before someone else did.
It was kinda scary how simple it is to adopt an orphaned package. Create AUR account... click an email link... Done. If someone wanted to squat the package for malicious purposes, it would be stupidly simple.
I get that this is a problem for all community repos, not just AUR (npm, anyone?), but it's still an unsettling prospect. I feel like it goes unacknowledged some times.
