IIRC I was the one who merged the posts (currently going through a large backlog).
As will be logical, an OP of a service topic cannot wait for someone to make a post before he can make posts about service updates. I can't help but respond to a post because I think I'll make a post hours later. I can't help but give information about the service, just because no one else has written a post since the last one.
If there are 24h+ gaps between posts, it's fine to post them consecutively as they become bumps. However, once those bumps are no longer new, they will be merged together - no action required on your part.
Furthermore, it is not appropriate to edit posts, because a lot of the information is relevant and serves to inform other users. Some of them receive notifications and it is useful to make new posts, with relevant topics.
And you're free to do so once every 24 hours. Once more posts have been made, the old posts serve little to no purpose notification-wise.
The most unpleasant thing, which led me to open this topic, was the fact that one of the deleted posts (merged with another) was the statistics post, which will impact the link in the official topic. (This link:
https://bitcointalk.org/index.php?topic=5450546.msg63126527#msg63126527 - regarding statistics [Oct'23].) Link that is not only in the official OP, but can also be in some translation topics.
In addition to having to change the link in the OP, these statistics will be mixed in with other posts that have nothing to do with the subject, nor with the organization of the topic.
As consecutive posts and bumps generally should not be considered stable (as in they might be merged with previous posts), my suggestion would be to have a single dedicated posts where you collect historical statistics with the bumps / update-type posts serving as merely updates with new stats to those actively keeping track of the thread.
Therefore, I suggest special care when dealing with topics (ANN) related to services. Because a change may require additional extra work without any need. An OP cannot depend on third party posts to make new posts, and be afraid that later these posts will all be together, when in this case it makes no sense at all. Of course, the idea of this post is just to draw attention to the topic or make it move up the page (which was not the case), it makes sense to bring all these posts together.
While I'm generally not against the concept of exceptions to the consecutive post rule for topics where it especially makes sense, IMO the seemingly small inconvenience of simply editing in the stats or whatever info you want to regularly post at the first of several consecutive posts (that is if the stats you wanted to post would become a consecutive post instead of already being sandwiched by other users' posts) warrants an exception.
