Before the word SCAM was used on hosts that really scammed you, took your money and left, never to be heard of again. Today forums fills up with scam threads, there people call a host a SCAM because they have not replied on a sales ticket on the weekend, when the opening time clearly is stated on their homepage.
My worst (and only one) scam was by a host called XenSpeed.net, back in 2012. They runned away with around $70 of mine. Paid for 6 months service for one server, and 12 months for the other, got one month service, then the servers went offline, and the people/person behind XenSpeed was gone for good.
I wonder how many times you have been really scammed by a host. Lost lots of money, time, maybe important data (of course, you are keeping your own backups ;)) etc.
If you want, can you tell how much money you lost?
