Doubtful, but their developer is a pretty cool guy, feel free to just outright ask him if your server is blacklisted (I can't see why they'd have you blacklisted; a large chance is that your host is blocking outside connections to file_get_contents).

Stop Forum Spam requires an API Key to send data to their database; a key is not required to send a remote query with file_get_contents, but file_get_contents needs to be able to contact to "the outside world" (some webhosts restrict remote content).
