Personally, this attitude of not wanting to discuss the project on the forum and only on Discord, is a source of doubt.
Toxic or not, I don't think it's up to you to decide.

If you want to make this project benefit everyone, and prosper over time, it is more than normal to publicly announce what it is about.

Because announcing the project only on discord, personally I already have doubts about its reliability and seriousness.

Of course it is up to you to do what you want. It is your project after all. But as investors for years. And given the number of scams that have been perpetrated, it is undeniable that this kind of behavior is still going on today.

Good Luck
