I have never in all my time on a computer put links in a post or comment that led people to other places away from the original site, it just totally sucks. It’s neither ethical or nice. It’s just rude. If you like something I write, no problem, and I have no problem if in the comment you post a link to your own site, but come on, its only fair that the comment get viewed too. If you post a comment and I look at it in moderation and it looks ok, so I allow it to be posted, know that I also look at the comment online and if immediately redirects, you’re outta here bub.
