Access has been blocked

While I may access my site frequently, I can’t think of anything that I do there that could even remotely be considered as spam, yet AVH First Defense has blocked me from accessing my own site repeatedly. Yes, I can white-list my IP but, since I use my Verizon Hotspot as an IP, the IP number changes every time I reboot my phone. Not only is this annoying to me, but I can’t help but wonder how many other people it is blocking from accessing my site. I know that I am not spamming my own site, yet it blocks me all the time. How many others of my site visitors are getting that nasty message that certainly doesn’t invite them to come back. I am just viewing pages on my site when it blocks me. I want spammers to be blocked, not random visitors or myself.
