I want to block entries like this. how can i do that

<Location ~ "/admin/">
Order allow,deny
Deny from all
ErrorDocument 403 "Sorry, you are not allowed to view this page!"
</Location>

this is not a good options. maybe "Ubuntu" or "Firefox/62.0" word good for blocking...

Comodo WAF can do that for easy way, just install it.

BUT... My experience tells me: they like to use random user-agent... so block user-agent may not really help.

but use Comodo WAF can block referrers too, I blocked china's Baidu, 360... that very annoying .

some clients didn't like WAF, so when they flooded by bots - we add next rule to Custom HTPD - Ngginx - Custom2:

Code:
