Going to answer you down here, but yeah I agree requesting brings us to the attention of posters and might entice them over here which would definitely help the community grow. I like the idea floated below of it being an opt-out request. I know it may come off a little rude, but some of the accounts for the most popular posts on the reddit are abandoned. The WoW one for example the poster was suspended by reddit and faik that was never revoked and OP didn’t make a new account or anything so there’s no way to reach them.
