There's an update happening everyday on our platform and how could a user browse if we will delete the past history post? I think it's not spam admin.
And also I Only post 1 a day if there's an update.
Compile every update log on the main post, and simply bump the topics once every 24 hours while deleting the past bump replies if you want your topic to be frequently visible. It's that simple. Probably set it like this:
August 22, 2019:
- Update 1
- Update 2
August 14, 2019:
- Update 1
- Update 2
August 1, 2019:
- Update 1
- Update 2
That way, not only it makes your topic cleaner, it also makes the user's experience better. Rather than scrolling and checking different pages of your topic just to track your website's/service updates.
