How I ban bad bots, spy tools and web scrapers --
you need root access in the server (VPS or above)
you will need to edit the root files on the server in SSH (or a local terminal)
you need rather obscure knowledge of networks, who to block, who NOT to block
you need to scan your server logs...
Attention: "role based name" email prefixes such as support, webmaster, info, contact, forum, service, affiliate, admin, traffic, partners, marketing, etc., for our member accounts are not permitted. They are acceptable for a vendor listing, but not for the member email. This is due to bulk email processors scrubbing them for delivery due to extremely high bounce rates. Please apply for membership using a personalized email prefix. Something like email@example.com.
If we discover you signed up with a role based name we will give you only one message to change it. After 3 days your account will be removed if the email is not changed.
