Difference is the Pianostreet text has links inserted in it.

I wondered about that, but didn't know the text was copied from Reddit.

Usually I just report the post to the almighty Nils and usually it gets taken care of.

Yes, this is obviously spam. Click the "Report to moderator" link as soon as you come across something you suspect is spam.

Thanks Nils!

It's just that this was being done is such a deceptive manner, users were spending time posting responses to threads they believed were genuine.

Might be handy though if users had to wait 3 days before being able to post a link - I feel this way, even if they do sign up and have to wait... they may forget about coming back in 3 days to post what they were going to originally.

I'm assuming that this thread, started by a new member, is actually an advertisement for the place in the link - an entity that has often posted in PS with links leading to their business.  The new poster "asks" a question, posts a link that supposedly gives answers to it but doesn't, and has not responded to any posts since.   Including my asking for clarification on what she is looking for.
