Just a word of warning, as this SE is now over 1-year old: if you asked a question that is 1-year old, has no answer, didn't get any upvote and has at most 1 comment, Roomba will delete it without notifying you.
I agree that some good questions escape our attention quickly, thus getting no upvotes and no answers. To spot these before they get Roombaed, I wrote this tool:
It shows the list of zero-votes/zero-answers questions, oldest first.
So, please use this tool from time to time, and for each listed question, either upvote it or close it (or skip it if unsure, of course). Thank you!
Soliciting votes in this manner goes against spirit of how we vet content, and we cannot allow this type of activity. While we encourage everyone to up-vote great posts, the motivation for doing so needs to be anchored in the merits of the post, not some other criteria like the post's age or something like this vote-by-request.
I do not suspect completely ill intentions in what you are trying to do, but anyone saying "contact me and I will up-vote your stuff" would likely result in a lengthy suspension for all involved and may even get their account removed.
