In this specific situation, it's rule 21 that applies. While "update"-type posts (like those in your threads) do usually contain valuable content which should be preserved, they're still bumps. While bumps are usually just deleted outright, consecutively posted old "update"-type posts should at least be merged. IMO it's a reasonable middle ground which both preserves the content (while the consecutive posts are deleted, the content from those posts is just copied over to the first post in a row) and reduces bloat arising from consecutive posts (removing the repetition of the thread title, report links, multiple identical signatures, etc.).
Since this is a more obscure case / interpretation of rule 21, AFAIK I don't think I've ever banned anyone for not merging their old substantial "update"-type posts. While I personally don't expect users to constantly worry about merging each and every one of their older consecutively posted "update"-type posts, in cases where I either notice or am notified of such posts I will merge them myself (with one of the notable exceptions being posts that are so massive that merging them hits the max character limit or which are IMO visually massive enough to cause extensive usability issues if merged).
You're free to post new "update"-type posts to your threads though. If an older "update"-type post of yours wasn't posted consecutively (as in the post before and after it are by other users), you don't have to do anything. If there are at least 2 old (a.k.a. not counting your latest one) consecutively posted "update"-type posts, I'd appreciate it if you merged them into one (at least once in a while) though I wouldn't sweat it if you forgot or only do so every X amount of posts / days.
This is just my interpretation, but maybe moderators think that posting just copy-paste titles with links as low quality post
and most of the merged posts you made looked exactly like that, one or more lines of the and original link.
I would not report this myself if I was a moderator, since this is posted in altcoin section that is usually much lower quality and I don't think this is done for increasing number of posts.
They probably would if someone reported those posts. Except nobody cares about altcoin threads.
Are you sure about that?
Take a look how many posts got reported by Ratimov, and I am sure lot of them are in local altcoin section.
Let's here what moderators have to say, and maybe we find the secret who reported them.
This wasn't reported - just part of my long overdue sweep of the first few pages of threads in Altcoin Discussion.
