Sorry to necro bump this post, but the other bumping service threads that I could find were started/died in 2016 [A], [B], [C], so this one is the freshest.
I have a thread: "Broadcast Your RAW Transaction" it's on at least one persons' list. The last post was 06 April 2019, 13:49:10 and my last last occasional bump was 28 December 2019, 05:46:15 (essentially three months ago). Some of the conversation in this thread has centred on if a thread peters out, then the information is not relevant. I disagree - I've seen some "pay me to shift your transaction on the block-chain" type threads. I would like people to know that a core feature of bitcoin is the ability to rebroadcast your transaction (for free) and would like to bump the thread something like once per month. Not too intrusive at all.
Other threads I've started that I would like to see bumped would be the
- [Guide] Broadcast Your RAW Transaction BTC & Alts coins - discussed above - once per month from last post in thread
- known alts thread - again not to intrusive maybe once per fortnight since the last post (that time-frame *nearly* happened not that long ago (for the first time since the thread was started), so a bump in that thread would be very seldom)
- Lightning Network Lenders' (and borrowers) discussion thread. - would probably bump once per month (after last post) to bring awareness about the Lightning Network to the forum.
- Timelord2067 - funds held by me 2019/20 - bump quarterly. (PM me if you'd like to know why)
There may be one or two more threads, but I would only be looking for a monthly auto bump of those threads.
While I've been typing this post, I see tranthidung has bumped a few of his useful threads:
- Make your topic title, posts more attractive
- Bitcointalk posting etiquette
- tranthidung's statistical threads on bitcointalk
so I'm guessing I wouldn't be the only one who would appreciate an automated bumping service on our useful, but inactive threads.
