This topic appears to be spam. Same guy was doing it on the BD forums a couple weeks ago with the same MO. He writes a seemingly legitimate question pulled from dialog in recent topics, and adds a sneaky redirect link at the bottom that points to his target site that he's trying to boost.
His link in the post above redirects to "20 Best Creative Mobile App Trailers".
I wrote a lengthy answer to one of his questions about CDIs, to then find that he'd deleted his post entirely because I removed his link.
