I can confirm that PvE and PvP sin both allow Darkmoons to invade. I've been invaded on multiple characters where I haven't even met any other players, but killed one or more NPCs.

You can also remove the sin for killing Gwynevere, which allows you to join the Darkmoons. Have you ever got invaded  after requesting absolution?
