Question about Necrobumping definitions

@CuddleWings or @Cream, I need please a bit of help regarding the necrobumping. The more moderator comments about necrobumping I see, the more I am unsure about correct handling. Please help

In the forum code of honor, the following is stated:

Spamming
- Do not create multiple threads of the same topic or discussions to overwhelm the forums.
- Bumping (repeated posting on a thread to keep it going or visible) is also not allowed.
- Necro-bumping is not permitted.

Unfortunately, it is not stated how many days calculated from the last post in a thread is considered necrobumping.

If I have a question, use the search function, find a thread which is some days in the past, but does not answer all of my questions: What would be the best way to handle my question? On one hand, we should not create multiple threads which might overwhelm the forum, on the other hand we are not allowed to do necrobumping.

Would it be ok if I create a new topic, add a link from the old thread, and write my question below or above this link? Or would this be considered necrobumping, too?

And how should I handle a thread where I simply want to get an update information, e.g. when you write that something is forwarded to the team, am I allowed to ask about news on this? And if I am allowed, in which way should I do this without getting a necrobumping comment?

Could you please add more information/clarification in the forum code of honor list? At least a bit more detailed definition for necrobumping in this forum?

Thank you very much!
