Ive tried a couple of referral programs myself, and honestly its mixed. The easiest way to handle it is to make sure you read all the terms carefully and dont rely on vague promises. On babu88play.org/ , their referral setup is pretty straightforward you can see exactly what your friends need to do and when the bonus will be credited. I found it works best if you only invite people who are genuinely interested, that way its low stress.
