I personally don't believe in blocking people no matter how annoying they are. Yes, there are quite a few posters on this forum whose keyboards I wish would melt, but blocking them is not a solution to which I subscribe.
I'm a very outspoken person, and as a result I'm sure I have been blocked by a few people. So be it. Everyone is entitled to their opinion, and on a forum that deals with something as complex as the Spyder, there is sure to be a vast array of different viewpoints. We may not all agree on everything, but blocking someone just because they hold an adverse opinion is rather pedestrian IMHO. If someone is personally attacking you in a relentless manner, than reporting them to the admin would be more appropriate.
Just my two cents worth...
