Given the feedback description, this could also be served another way: on a profile page (or wherever you can get a solid overview of your own roleplay ads), each rp ad can show up with a private/public toggle. It should be called by some other name, e.g. inactive vs public, to convey what is effectively happening with a private roleplay ad.
It isn't one click, but you can rapidly set which ads you're interested in showing at the time, and which ones you aren't. This should not have a timer for flicking back on. Anyone uninterested in displaying any ads at all can leave them all off.
Wrecked Avent: the solution you propose sounds like what was discussed ages back about a looking or not signal, but the temporary on/off switch doesn't seem appropriate here.
I am here for roleplaying, but even when I am I may want to not advertise. Actually, especially when I am: if my schedule's full my natural response would be to stop advertising, or not start. If I have some great roleplay ads with ideas I'd like to play out someday, I would rather keep them and hide them than delete them.
I wouldn't want it to periodically flip back on - I went through the process of hiding them, when I'm free I'll know how to go back and switch one or two ads back on according to what is suitable for me at the time.
This has the added benefit of servicing people who are advertising actively, but aren't in the mood for certain things.
