Poptm popunder, known problems?

[porn-update]

I would add the poptm (poptm.com) popunder on my sites, but because in the past I've had bad surprise, I want to first ask you

There are known problems of poptm? For example, it is disliked to the search engines, or after a while earnings go down drastically, etc.

poptm also provides a script in php for pop-unders, is the first time I see him, I would use, has anyone tried it? Problems?

Thanks

there is long thread in Digital Point Forums about Poptm, perhaps you can find answer there

Thank you, now I give a look at the whole discussion

At least here they answer questions, are three days that I opened a couple of tickets on poptm and I was not yet answered any ...

Not really a nice start ...
