Thankfully none of my clients host with them, but we still have a few clients who use them for dns and the domain registration. Funnily enough I got an email extolling the virtues of their security if I purchased an (overpriced) ssl certificate from them. The irony of the big security issues was obviously overlooked by the marketing department who had not realized they had a major security incident at the same time. Oh and don't forget the spammy - you need to renew your domain now (in Feb for a domain that expires next November) and the stupid icann agreement emails that you get every month or so....ugh.
