You can tell a network is struggling when they're so desperate for traffic that they start spamming your whois protect contact.
I know all networks spy on their affs / creatives, but it's real hard to trust an aff network who is openly snooping through your campaigns. Also, I doubt this network could come within $3 of my payout despite their lofty claims. And no, it was not PKM.
my 2 sen....
I followed up on a few emails I have got like that over the years and some turned out to be decent contacts....not all but some...
and if you think about it that person has made the extra effort to try to reach you.....could be a sign of good work ethic....most guys would just give up when they see your lp and cant find any contact info....
I think one of the things thats hardest to do in this biz...is to keep an open mind when 90% of this biz is utter BS....
just food for thought.....
I agree, i've had good and bad experiences being an affiliate and having AMs reach out to me based on whois/seeing ads etc..
Sometimes it's worth investigating, unless the message is extra slimey.
I think it's fair game.
It gives you a decent bargaining position if they already know you have good volume / active placements.
The type of spam I hate most is anything with Mike Fucking Filsaime's name on it. Or Pace Lattin.
+1 to what all the guys have said, I also got contacted by one of my current top networks out of the blue.
I got a similar message from someone last week. It just turned out that I was ALREADY pushing traffic to the network he introduced in the email (on other offers). Now I know for a fact that this network is VERY badass when it comes to offering high payouts, weekly pays with slightest of traffic & an amazing affiliate manager who reaches me out very often to discuss more business. So its good that you were approached. Gotta have an open mind bro 
I think that's the exact opposite.
If an AM is going through all the trouble to buy accounts on spy tools , do his research and email on your whois email means he knows his stuff and is a hustler.
These are the kind of people that will help you move forward.
You guys all make great points and I realize my initial post may seem close minded without a little more context and I was wrong to paint the situation with such a broad stroke.
That being said, I know the network and their general reputation is rather sub par. I am also direct on the offer, if they were really these allegedly intelligent, hardworking hustlers, they should have seen that there were no redirects and realized that I don't want their brokered payout when I'm already direct with the advertiser.
I disagree with that statement.
I think a struggling network can't support staff to do things like this.
This was a hallmark for Clickbooth and Azoogle back in the day. Actually required for all new AM's
Actually, I'm still working with a few networks that their AM's contacted me directly from this forum. And yes, one of them is PKM and they have been great.
Also, I've earned most of my profits from weird obscure small networks, some of them already disappeared.
Whereas I have 5 years old accounts with 2 of the well recognized networks, I've tried to contact my AM for a year with not avail, and the other network keeps replacing my AM every other month, what gives? I'd run traffic with real ppl that are always there for me 24/7.
PS: Andrew where are u bro? the sky will never be blue for me
