You are definitely wrong. I've dabbed a q-tip soaked in denatured alcohol on sticker residue several times.
So much in life depends on the skill of distinguishing the people you should listen to from those you should not. Personally, when dr.grace says something even modestly scientific, I tend to listen. But that's just me.
It just depends on the plastic. Sometimes people may sound overcautious in these matters because they are thinking primarily of vintage pens and of modern luxury pens made with celluloid or other plastics that might be selected for their beauty rather than their chemical resistance profile. Celluloid will definitely be damaged by exposure to alcohol. However, most of today's resin pens are made with PMMA, I think, and PMMA has very good alcohol resistance. I would guess that Pilot is using PMMA, so I do not think an 823 is likely to be damaged by brief exposure to isopropyl or ethyl alcohol. Going back in time, however, one does not have to go far to find pens made with various plastics that will craze or even begin to melt when exposed to alcohol. Take a Sheaffer Snorkel or Touchdown, for example. The effect is instantaneous and obvious.
Having said all that, I probably wouldn't use alcohol because it isn't very good at dissolving the adhesive. It's a lot better than water, obviously, but that's not saying much. I do suspect original Goo Gone is probably going to be OK (if WD-40 is), but since the adhesive will rub off over time with no intervention at all, caution is wise. A high-quality, very sticky tape is the ideal approach...if it works. Only one way to find out.
