It could also affect your connectivity, and if your personal workstation is 
at work, your employer's connectivity.  It is not necessary to have your 
list hosted for this type of list management to be a violation of your 
ISP's TOS.  Running this type of list on your own machine at your end of 
the connection is also a violation unless your ISP is "spam friendly".  If 
a responsible ISP gets complaints that your machine is spewing spam (e.g. 
sending bulk unsolicited email to people who didn't sign up for it, due to 
the fact that you didn't require confirmations for all list subscriptions), 
they are not going to just let you keep on doing it.  Some ISPs shoot first 
and ask questions later, so the first you hear about it (from your ISP) 
might be when you can't connect to the Internet because your link has been 
cut off.
