This was the first time I received this, so I checked my other two sites, and they all barred me.
I checked the email logs, and it appears that I had looked at the site multiple times in quick succession when in fact all I did was attempt to view the index page as any other user would do.
The email log states
IP Address: 90.200.XX.XX (IP Lookup: IP Lookup)
Reason: Admin IP Whitelist
and another log raised seconds later states ...
IP Address: 90.200.XXX.XX (IP Lookup: IP Lookup)
Reason: DFIShield
I can add my IP to the whitelist which will stop it, but my question is ...
How did Admin tools believe I am a security exception with me simply viewing a page on my site, and if this has happened for me, would it happen to any other person viewing ?
What is the best way forward for this ?
