Yes, there are a TON of these lately.
Stock posts about social media marketing, personal branding, landing page tips, job hunting, etc.
A growing number of them are posts I find elsewhere online -- lifted and a few sentences changed. And it's not just happening here on Indie Hackers. It's happening all over the place. Not hard to spot when you start to look critically.
I'm not saying these posts aren't useful. But it's spam, nonetheless.
I could literally point to a dozen more just like this, many with dozens and even hundreds of likes and comments.
Again, this is useful information. But the author should really be giving credit. Otherwise this is just spam.
