Depending on the ip space I find FTP brute force attacks 10 times more
common than SSH attacks. There really isn't a blanket rule you can impose.
On a different note, unless you clearly advertise that you're offering
filtered services I don't really find the practice ethical - and no a
tiny line in the TOS doesn't really cut it IMHO.
That doesn't mean it can't be done, simply spin the imposed ACL as a
value-add and that your customers are now on a "safer internet".
