I can understand that some providers want to connect only by e-mail.  I even understand (despite disagreeing with) the whole give me your name, phone number, job address, etc.  But I cannot abide a provider whose site traps your computer with cookies so that you practically have to disconnect to get out of their site.  Seems to me this is what the low-end porn guys do to trick people into signing up for service they don't really want.  I've noticed a couple of independents as well as some agency sites that do this.  Annoying.
