This is a very strange argument here. Noone here is claiming they agree that an Affiliate Manager should PM each and ever member of this forum, however, if someone sends you a specific message relating to your site, it really shouldn’t be such a concern.
Wikipedia defines spam as “…. unsolicited and sent in bulk” (see en.wikipedia.org/wiki/E-mail_spam).
I also don’t go through the members here and invite them to come, as it would be a waste of time, but like Renee, I often look for and email appropriate sites that may be interested in working with us. If they arent interested, they generally don’t respond or politely decline, it isnt a big deal.
