Hi cully,
I'm fairly sure that the administration has found the problem to your problem not being able to post a general ban for the 88.0.0.0 was put in place. It is being modified to reflect only the series ( 88.0.0.0 thru 88.255.255.255 ) needed to ban the proper countries with problems of Internet enforcement there are lots of ISP's in this range from many countries in Europe not just the UK unfortunately.
ie: Your UK ISP series 88.108.0.0 - 88.111.255.255
I think the administration will be changing this along with some additions this weekend.
Thanks,
Fuzzy
