Go to google then type "name of program" -scam ...
then you should be able to see if there are any complains about a
particular program...
bear in mind that all programs have some sort of criticisms... but
the most important thing to look out for is whether there are
complains about the program not paying people money....
If no one complain...then it should be a good/honest program... if
there are complains, but also a few praises here and there.. then
be a bit more careful , as the praises might be the doing of the
program owner...
