For those who are sucessful at adult dating, do you create your own banners or do you just rip from spytools or manual spying?
I learned that banners burn out fast, so how do you keep up with new banners? If you just rip, I think you will run out of banners to rip. So do you create your own banners too?
If you create your own banners, any tips to be most cost effective and time efficient?
Creating your own banners is pretty much a must.
You can be lucky and rip a good one for sure, but chances are you will often run into ads that are already burned out, not good in the first place, built for specific audience etc ...
The good news is, you can kinda resort to ripping the banners anyways, just change them a bit once you do. Quite often, all it takes is to replace the female on the banner. Or change the color, or modify the copy a bit.
I also browse the spytools or websites, rip the banners I like, but then I make the mentioned changes.
Swapping the photo is easy, you can do that with photoshop or some other tool. Animated banners are a bit more complicated, since you need to edit every frame, but still doable. I have a designer at hand, so he always does this for me... doesnt take him more than a couple minutes to edit a banner... so with some experience, there is no reason for you not to be able to do the same 
In addition to above points below free tool is very useful in creating or editing the banners:
