I think the current problem is about diversity. The forum still attracts more than 6 signature campaigns, but most of them are gambling campaigns. In the past, options were available between ICOs, crypto exchanges, mixers, tokens,...etc, but since 2020, most of the promotion has moved to social media. Then the options became between mixers and gambling, and mixers were banned.
If gambling campaigns find another place to promote, they will inevitably stop promoting here, regardless of the quality of the posts. This is what happened with mixers, which was moved to another forum, although the results was not guaranteed.
The beginning of solving this problem is to rewrite the forum code and attract more beginners (activating the YouTube channel).
