I didn’t say anything about self promotion because I don’t usually have issues with that.

This isn’t self promotion. As I said, this is pure advertisement.

Self promotion would be someone who is or has been engaging with the community or the wider fediverse at all that does something like “Hey, I did some research on this topic and there’s some things I think people should know about it so I wrote a blog post. Let me know what you think!”

This also isn’t just out in the open. Why would this person set a different display name on their account unless they wanted to add a small delay in people catching onto this? Instead of a direct “this is the site I run”, their profile has some weird promotional wank about the site and a link. It’s not direct and up front.

Just… any attempt at bare minimum effort to indicate that this person had any intention of actually engaging with the community instead of dropping a link and running would have made this more palatable.
