👋 No hard at all actually. I never saw myself to belong there anyway. I am still part of those groups and check them out occasionally but what I abandoned was the idea to have them as users :)

Thanks for the compliments Dmytro! I use three ways primarily: SEO tools, to find keywords from posts from users that use competitors apps. This took me to these users' profiles. a bit more advanced Google and Twitter search to find users that are looking for alternatives of these tools, and I set a F5bot reminders to get notification every-time someone mentions a competitors app on Reddit or HN.

You will need some form of a Backend to which you will direct your requests and take full control over the request headers. In my case I wrote a Node.js backend to solve the problem.
