Re links to knives for sale, on ebay or anywhere on the net:
For the purpose of shilling -- NOT ALLOWED. Doesn't matter if it's your sale or someone else's, it's still advertising and NOT ALLOWED. If you want to sell a knife you can get the appropriate membership and post in the appropriate forum. If you see someone else has a knife for sale and you think it's a wonderful bargain and you want to tell your friends at Bladeforums all about it and you're so excited you can't hold it in -- well, life is tough and some people have to learn the hard way. Maybe someday you'll learn not to post spam where it isn't wanted.
For discussion purposes: that's different. Watch out, though -- a couple of times people have seen an offering so ridiculous they wanted to give everybody the chance to laugh about it, and posted a sarcastic message about what a wonderful bargain it was, and
didn't show any sign they were being sarcastic.
I got fooled that way a little while back in
The SPAM of a life time!!! A member reported what looked like spam to him, I responded and it sure looked like spam to me, so I despammed it. I didn't even follow the link first. Then the author of the post wrote me a nice email apologizing for the confusion and explaining he meant that sarcastically, so naturally I apologized too and restored the post.
More recently the same thing started to happen, but that time the author of the post didn't write a nice email explaining; he threw a hissy fit, and things got worse from there.
Just try to keep in mind spammers often use very exaggerated language. Just because you use a lot of exclamation points doesn't make it clear you're being sarcastic; spammers use a lot of exclamation points too....
If it's an auction the safest way is to wait until the auction is over before you post about it. Then no one can mistake your post for shilling. If you want to post about a knife that's currently for sale, just make it clear you're not trying to get people to go and buy it -- make it
very clear, so clear a moderator who's in a hurry and hates spammers can't misunderstand. We all hate spammers and we're always in a hurry when we respond to reports of spam.
