Unfortunately, though, most “brokers” as horrible as this are only too happy to pay people a little, by the post, for favourable forum mentions in any context at all: it’s pretty hard for them to get customers other than through fake, incentivized recommendations.

Sadly, a handful of people may even believe it.
