I think I thought it through pretty thoroughly. Like I mentioned, my concern is professionalism and at least the appearance that someone cares. The posts haven't been touched, and are telling me I should do something which isn't possible given the laws governing space and time. The wording is "Be a subscriber by May 4th to receive..."
I didn't say they should remove the postings completely, but how about instead of telling me to sub two months ago, they change the headline to something more current? There are numerous solutions, if they want to keep the overall content as some sort of advertisement.
