Hi,
when you search a program include words like “warning, late payment, no payment, haven’t paid, predatorial” those are good words to start and you’ll spot other red flag words as you go.
those would be the definite programs you would not want to consider then you can fine-tune your search perhaps based on checking out a site from somone who’s posts you respect (you may not know who that is now but by the time you finish searching the first paragraph you’ll have a better idea) and seeing who it is they are promoting upfront.
above advice should be done in order … there is no short cut without risking dire results. Know which places to avoid first and then make your decisions on who to promote. I tried taking short cuts on this formula and ended up promoting a program I would have never touched if i had searched them first. Not every webmaster has every site up to date with what is best for you. But its a general good place to start finding programs that will pay you and are aff-friendly.
