In other words, there is no policy re. frequency of posts, as long as the posts are not spam. Correct?
There is none. There are people making a lot of posts (20+) a day. However, what you are doing is 'bumping' the thread by posting 'updates'. Rule 13 applies to that.
Suggesting that my posts are no more than 'bumps' is a bit... disengenuous?
Especially in light of the 'bullish news' sister thread remaining unmolested, while having x10 the number of posts per day (see link above) & the posts being >80% a simple screencapture of a news article, with no additional content.
Now tell me honestly, did you delete the post because you thought it a bump, or ...for other reasons?
