Why would you think you'd be "blacklisted" just for not having what a lady requires for screening?
Unless, by "blacklisted" you simply mean that she won't see you. Which you can expect to be the case.
But that's not what blacklisting is; real blacklisting can be pretty serious, and the majority of providers (especially those of solid reputations) do not do this lightly.
As others will no doubt suggest, you should consider joining P411 or Date-Check, whichever seems to be more commonly accepted in your area. And then look for newbie-friendly providers on those sites.
Or start hunting for newbie-friendly ladies/agencies who will verify you via other methods; that often means giving out employer and other information.
"Light screening" can mean a variety of things.
If you're planning to use the providers you've already seen as references, it would be a nice touch for you to ask them first if they're ok with that. But if they don't actually reply to another lady requesting a reference, there's really nothing you can do about it. The lady you are trying to see may offer an alternative screening option, but then again, she might not.
Try to learn all this right off the bat. If you're not sure from her ad/site, then ask her directly.
I'll step back now and allow the hobbyists to provide the perspective I cannot.
