Strange question I know, but is there any way I can block certain IP's from visiting a website (a paid host, not my own machine!).
On a slightly different angle, most ISP's block certain ports because they are known to be trouble in terms of spreading worms and virii etc. Should web hosts adopt a similar attitude, and if so, is it possible for a host to easilty bloack access to their servers on particular IP's?
I speak from the perspective of someone who's sick of clearing spam from a guestbook that's been left there by some kind of script (related to freeyaho.com - don't visit the site unless you are NOT still using the MSVM, and are reasonably well protected, including a pop-up blocker. It's dodgy, and I don't know what it's serving up altogether), and have recently found that someones taken to signing up to my phpbb2 forum just to leave a spam website as their profile homepage. I'm sure that someone somewhere knows where this stuff tends to come from.
