Now, I would normally agree with you if the site actually directly linked to anything that was yours, whether it be an actual download link or a website you created about a project. But in this case they're all links to posts you made on a forum that is not owned or operated by yourself (excuse the pun). The posts, therefore, do not belong to you (even though the content, in most senses, does) and demanding that they be removed (rather than politely requesting in a PM sent to creator of the site) isn't fair. Also, by having those links removed, you would be making it more difficult for people to find your creations. These forums aren't as well categorized as the website is and using a search engine often requires some trial and error with the search terms. Demanding that they be removed on the basis that you might
one day to decide to have them removed (why?) in order to avoid PMs from people looking for download links just seems selfish.
Jeez, man, just drop it.
By posting it here instead of sending a PM, you've allowed anyone to comment on or argue with things you have said, whether or not it was directed at them. Additionally, by posting such a confrontational reply, it has become my business to prevent a conflict between you and some other user. I pointed out that you shouldn't be making a demand like that and even tried to give a suggestion to solve your problems with the site. It's really okay if you don't want topics that you've created linked to, but you need a better way to express that than with an impolite demand.
