You really shouldn’t answer questions you clearly don’t know the answer to. There a dozens of ways for apps to report your license status. Most people just don’t know about it.
You can look at a MS Word doc someone sends you and detect the license. Apps can phone home all the time to report your status. Just because you’ve never noticed ot or no one ever caught you doesn’t mean there’s ‘no way’.
I honestly am baffled when people take time to type this type of crap out and post it. You clearly do not know, but you posted it anyway AS IF IT WAS FACT, despite it being provably false.
In my personal (and therefore, limited) experience, engagement is much harder to get in the fediverse. I hope it improves, but it’s not easy to find people you don’t know in order to follow them, and vice versa.
