XF 2.2 Getting blocked by firewall

[neon tetra]

Some of my forum visitors have informed that the site gets blocked by their firewalls esp when on wifi while other sites work just fine for them.

Would appreciate some assistance what could be causing this?

Perhaps their firewall doesn't like the word "mafia"
