Anybody that promises you a guaranteed subscription rate is not above board in one way or another.
How traffic converts from one site to another is a matter governed by a very large number of factors, typically if you sell balsa wood aircraft advertising on a site for knitting supplies is not going to net you a lot of customers.
I've been 'helping out' a fellow HN'er with a bunch of traffic and to date we've yet to see a single conversion. That doesn't mean that his product is bad or that the traffic is lousy, it simply means there is an impedance mismatch.
So you can only determine what works and what doesn't by trying it. But once you are spending money on clicks then that 1% is a good ballpark figure because that's what you'll need to make money on your traffic buys unless there is a scam involved.
On 'junk' traffic (exit consoles and other bad tricks) conversion rates can be as low as 0.01% or worse, on good or great (matching) traffic it can be substantially in excess of that 1%. Audience match is key, and that goes for any form of traffic buying, adult or non-adult makes no difference, if the user lands in something they didn't expect on the 'far' side of that click it had better be a positive surprise or you've just effectively made your precious domain worth less.
