I have hit the looper button a few times by accident when reaching for FX II or III.
The LOOPER button doesn't appear to rest too close to where the main action is at least not more than any other button of the Remote - I would say it's the least exposed button. Do people also hit Up while trying to select Slot 1? Or the other way around? Or Down while trying to select Slot 2, or Effect Button 4 while entering TAP tempo? Why are accidents only reported regarding the LOOPER button? Or why is it so much more "embarassing" ... just the LOOPER button itself doesn't change any sound nor does it launch any looper activity. It's like the TUNER button without "Mute Signal" being ticked. Just hit it a second time and done. To me this sounds like a challenge of the concept of footcontrollers in general!?
