[Kickstarter] Provide clearer guidelines on handling marketing emails

I'm running a Kickstarter right now and have been bombarded with emails of bots posing as people telling me they want to give me advice on how to run a successful Kickstarter campaign and they all say the same things over and over again which I'm sure we've all seen posted here. these all end up asking me to pay some sort of fee to have an agency look over my campaign and give me more advice promising to be get a bigger audience etc etc. typical grifter bot sounding stuff, my question is if anyone actually paid for this stuff? can it possibly be worth it? what was your experience? did they just take your money and run? I've everything on my own on my Kickstarter and it's on its way to getting fully funded and I used no bots or marketing "agencies". it's been a bit of struggle but it's no different than trying hard in anything else.
