I may be in the minority, but why are you complaining about tape? As long as what you are getting arrives safely and not damaged, I see no reason to complain about tape on a toploader. We are trading for cards, not toploaders.
I agree with this sentiment. The only cards I have access to are my tradebait (being in the military, I've packed all my commons up in a closet), so I don't have any 80s commons to fill up the toploader. So, using tape on a toploader is a necessary element to ensure your cards arrive safely.
I understand masking and/or painters tape may be more desirable for various reasons, but at the end of the day - all I want is a nice card and I could give a rat's patootie about the toploader.
Not using tape is certainly a personal preference that many might agree with, but I'm not going to give my trades much thought in this regard unless someone posts "TAPE-FREE TOPLOADERS REQUIRED" in the trade manager.
Just my 2 cents.
