You asked for trouble, and you got it, even though you may not have had malicious intent, no one can be sure what would have happened if someone had taken your proposal seriously and sent something to your address. Such things should definitely be rewarded with negative feedbacks, although in this case there is another side of the coin that says you are just an ordinary troll who has gone a little overboard this time.

I think both members did the right thing at the time, and it's just their decision whether to stay behind their initial feedback - stop teasing and trolling people around the forum, there are many other platforms where you can do it without any problems.
