I got calls from FE IMO's to website advertising to selling a host of other products from robo calls. It sounds like a bombardment of it coming in these days as more folks are avoiding the high costs of mailing or an expensive "legal" telemarketing outfit.
As long as it remains to be a much more cost effective way to run it while producing the returns they will be around until there is a bigger crack down on it which most likely will never happen.
The thing about getting those calls about insurance is that they are calling B2B. Even if you're working out of your home, just the simple fact that you have your license allows them to get away with it by justifying that it's B2B.
