As someone who created and still maintains the unofficial list of rules, it might surprise you to hear that, well, I don't know. If you wanna err on the side of caution, bump one thread once every 24 hours (doesn't have to be super exact, just make sure that your previous bump post doesn't have the "
Today at ..." timestamp). Doesn't have to be the same thread each time but pick only one for your daily bump. If you really wanna test the limits (this
isn't a suggestion or endorsement of such behavior BTW), bump all of your threads every 24 hours. Do note that I
can't guarantee you won't get banned for doing so.
Searching around for what theymos has said about bumping turns up mixed results. His old posts (from nearly
8 years ago) hint at a slightly different version of the rule (both stricter and more lenient in different regards) than what I've noticed being enforced right now (emphasis added by me):
<...>
Do not bump more than once a day or many times in a row, though.
<...>
No more than once daily. You shouldn't bump a post too many times in a row. Bumping shouldn't be annoying. Delete old "bump" posts so they don't clutter up the topic.
You can bump no more than once per day, and not more than three times in a row.
Mods also may take action if bumping becomes annoying in other cases.
<...>
He's not just bumping -- he's also adjusting the price, which is more meaningful than the typical "bump reply". So that guideline (no more than once per day and a few times in a row) doesn't apply.
Considering how much the forum has grown (as well as factoring in my experience on how it's been enforced for a while now), I really doubt this version is still in effect. That and the 2 newer posts I managed to dig up which seem to (at least vaguely) reference the rule listed in the unofficial list of rules (again, emphasis added by me):
<...>
Posting twice in a row within 24 hours isn't allowed even in selfmod threads because it unfairly bumps the thread.
<...>
<...>
- Although bumps every 24 hours are allowed by the unofficial rules, should they be allowed?
<...>
Which all brings me to the conclusion that... I still don't know. If you want the definitive answer, I'd suggest PMing theymos about it.
tl;dr Exact rules? I don't know. PM theymos about it
