BBB is also a kind of scam: they are not in any sense a government agency, more of a Yelp-like entity. In the age of the internet, they go after small businesses, and are eagerly sought out by scammers because you can just purchase their approval, and it can help allay people's suspicions. For that reason I'm less trusting of anything that is touting BBB support. It might be an old person who's not up to speed with what they've become, but it might be someone purchasing a high rating because they know they're going to try and rip people off, and need some cover.

At the time of writing this, they think I'm just dandy, because I didn't respond but didn't attack them when they tried to shake me down. It'll be interesting to find out if they respond to this post ;)
