not really. 

the polar other side of your opinion is my opinion :)

people supporting and paying money to resource whores who also are non
responsive to abuse complaints and whom also may host criminals and
other scumbags deserve to have their email refused :)

the days of 'bullet proof' hosting are nearing the end as many mail
server admins are simply tired of constantly trying to do battle with
snowshoe and other rubbish.

of course, again, best practise is not to 'drop' but to score email
incoming from abusive hosts and IP numbers as well as bad places on
the net, and at first mark them as spam, report that spam and then,
eventually, these resources will also end up in a permanent drop
dnsbl :)

does your list require people to opt in? or are people simply added and
then expected to unsubscribe?

see, sometimes 'people' are not real people, they could be data in
stolen databases, they could be submitted by devious 3rd parties to
cause your list harm, there could be so many issues...

If you are just adding email addresses to your list :) - then you will
find yourself experiencing issues if something goes wrong and you are
reported somewhere...
