IP Blocked Using APF Firewall But Still Accessing Usign PageNest

I'm having an weird issue about PageNest, an offline browser which somebody is using to copy my website and the worst part is makeing my server run slow i think because of to many acceses.

I have tried to block his IP using APF firewall

/etc/apf/apf -d xx.xxx.xx.xxx

After this he is still on top of the list (netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -n)

341 requests from his IP

I checked the apache status page and he is still there too , and cPanel's Latests 300 visitors, the same he is copying like 16 images / second

/photo-gallery/toyota......
Http Code: 200 Date: Feb 19 08:11:59 Http Version: HTTP/1.0 Size in Bytes: 2927
Referer: http : // www . mywebsite .....
Agent: PageNest Pro/3.04

I tried than to block myself and it blocked me I wasn't able to access those pages that he was able and I used the same command for bouth IP's (his and mine)

Any ideea how come he's still able to spider my website ?

PS. in the mean time , as I saw that he wasn't stoped by the APF I added 3 lines of PHP code into my function.php file :...
