I got an interesting message from someone today via the BE contact form. However, they let me know that if I replied via email, then Spam Arrest would ask me to verify myself.
I've not heard of, or even thought about, SA since their big scam several years ago. So I did an Internet search to see what people were saying about them. I found plenty of stuff about their scam.
I think what outraged people (including me) the most was that a so-called anti-spam company, went and spammed all their own customers' correspondents. I think they'll never live that one down because people have long memories about abuses of trust like that. Even so, they do appear to still be in business.
I guess my best bet in this particular case is to reply to the person using their website's contact form and tell them that I can't enter into any email correspondence with anyone via SpamArrest as, having been scammed once already by SA, I simply can't trust them. Pity, because I liked the person's website and what they were offering.
