If you posted affiliate links, yes, they were deleted. Depending on how you got to that product page, sometimes just copy and pasting a link uses the affiliate link. Basically, that means if someone buys from the link you provided, somebody is getting a cut.
If you post a simple link to a product, that shouldn't be an issue. I find I have to strip out a bunch of the added URL stuff to whittle it down to just the product.
Will doesn't even put his own affiliate links in here, so it's not accurate to assign the forum as a for profit enterprise. Per rules and practice, it's an anti-profit environment even for the owner as a direct. The only way it becomes a profit center for Will is if a user goes to Will's website and generates revenue from there.
