Yeah, i use this technique - both a simple blocking appointment as well as a fake meeting with only myself...but what has even happened a few times is that someone will see that i have an appointment or meeting near the end of the day, and they figure they can book a short meeting with me immediately after that block...I have a colleague at work who from about 6pm until the following day blocks his calendar with an "out of office" signal...so its 100% clear that he is off the clock and not available...but still people in this company (from other timezones mostly but sometimes also the same timezone) harass others regardless if a calendar os blcoked, etc...Like i said its simply toxic where i work in this way. But, i appreciate the idea, thanks!
