You have said it all, dear. Write genuine, and make time to engage with other writers genuinely.
Get these two done and you are on the right path of earning 3× your previous month's earnings or even more.
Concerning spammers, I don't know if it's the right advice, but I block them on sight; I hope you understand what I mean 😁. I value my words as much as I value myself, therefore I give no room for fake engagements.
