I guess some of our older users have just been burned by some astute spammers who come to BLF posing as users with questions about a product. So I don’t think it matters whether it’s a link to an expensive brand or a budget brand; they (we) just simply make mistakes sometimes.
With that being said, I created BLF principally out of my frustration with other flashlight sites that prohibited posting links, and we had to refer to specific products as “SKU #4653 on DX”. So as long as the user is asking a legitimate question and is not a spammer, posting links is actually encouraged here.
