Well, you said to PM you, if anyone needed help setting the same thing up. (Or something like that.) That's advertising your services.
I didn't report or anything, but when I read it I remember thinking it would probably get pulled.
ETA: D., it wasn't what you said, but how it was worded. The way you worded it made it sound like a solicitation. I knew it wasn't, but when I read it I figured someone would think that and report it.
Next time, why not say something like..."I have a lot of ideas about this, but it's not a question so I'll leave it to PMs. If you want to share ideas, please PM me!"
