Its a shared server, so some other domain on it triggered the block which unfortunately hits the whole IP. Apparently the malwarebytes people contact the host about the offending domains as a standard procedure, and since hosting malware is an obvious ToS violation the hosting should shut down the sites and then the IP will be cleared from the blacklist. The block should be temporary depending on how fast the host works, so you probably don't want to disable website blocking permanently.

There is a way to set it to ignore it (you may have to update to a newer version of malwarebytes since this feature may not be implemented in your current version): Visit the blocked site and incur an IP block. Then right-click on the Malwarebytes Anti-Malware system-tray icon after the block notification appears, and choose Add to Ignore List and the IP.
In the future, IPv6 should help prevent incidents like this from happening because there will be so many IPs that each domain could have its own unique static IP even if multiple domains run from a single server.
