I wont help you and i will tell you why:
The main reason of that whole thing is, i don't know what values your community stands for at all and i dont feel connected to it.
Beside of that, i dont really have that much time and prefer to invest my time in other things like blob.cat.

Beside of that i want to tell you a few things, lets start with that blogpost:

You claim that you cant search for sympathizers & members on mainstream social media because all of that has been tapped, censored and controlled: I do have a few issues with that. Look, when it comes to communities, I separate the personal communication with the public appearance of the community. Means, the community intern communication can be on a different channel than where you actually present your community. Compare that to how a company communicates. If you handle it like that, it doesnt matter which platforms you use to present your community, choose all of them. It also doesnt matter if they "tap, censor and control" your public pages.
Beside of that, what your community does and plans, should also be transparent, after all, you also want to get feedback about what you are doing.

For the private communication between friends there exist many tools, one of them is the fediverse, one of them could be matrix. Im a bit surprised that you choose something that is not privacy friendly like buddydo (never heard about it).

And now the ideology: I prefer structures where one decide together whats going on and not where one single person defines what the community does since a community is defined by the all of their people and not by a single person. Beside of that, im already part of way too many communities which have similar goals.

In general, this instance here isnt made to search members for your community. Let me define the boundaries: I dont have a issue with you posting blog articles or communicating with other peoples, if i like what you do, i will repeat it. But the boundaries stop when you start writing to random people directly and try to convince them of your idea. It is difficult to set clear rules, but before I do anything, I will first seek dialogue. It is difficult to set clear rules, but before I do anything, I will first seek dialogue.

And last but not least, i recommend you get away from gab immediately. Gab used to be part of the fediverse, not anymore and no one here likes gab, especially because their ideology reaches from alt-right propaganda to conspiracy shit, so imho you dont want such people to join any community.
