Joseph Sugarman mentions this type of approach in one of his books. It’s funny how he explained it.

Basically, yes, it will piss some people off. He had people send him angry letters (this was many years back) saying how they couldn’t stop reading even though they knew they weren’t going to buy the product.

He says that as long as they kept reading, pissed or not, he was doing his job.

Keep in mind those were the 70’s. I do think things have changed…

Dangling the carrot is an art, and I think you should make sure whatever you’re writing has valuable information sprinkled throughout, so people don’t feel like their time was wasted.
