The firewall at my 9 to 5 prevents access to Affiliate Future and any of their affiliate links. These are classified "Pay-to-Surf;Productivity PG".
I've not seen this for any other networks, which seems a little unfair on AF. Not sure where my company gets it's list of banned sites from, or if this list is used by other organisation companies, but I think AF should maybe investigate. I for one do a lot of my shopping at work (dinner hour only of course), so they could be missing out on a fair bit of business.
Actually, thinking about it, this was the case for
AW for a couple of months, but then normal servie was resumed.
