Crunch numbers always.
Sometimes the illegitimacy of a thing is hidden in the numbers. Many Online Reputation Management services are scams because they start out charging a low fee for services and then they roll in many hidden charges that oversell the product.
Appraise the value of the services you need from a general financial resource. Don’t let the company tell you that hidden fees are normal. Find out for yourself what the services are economically worth. You should not pay more for added packages you didn’t solicit, to begin with. This is parasitic at best and at worst could be stealing your information at a slow bleed.
