Hey Mate! Thank you for sharing. It's always interesting to hear about the 'crowdfunding marketing companies' that are popping up.
I believe Kickstarter doesn't allow more than 10 messages sent in a row otherwise the account gets flagged then reviewed by their team (with further action completed accordingly). Unfortunately all that happens now is that these businesses pay people to constantly create new accounts and continue to send thousands of messages a week.
Now I have no problem with people doing this, assuming the services that they person was offering were top notch and legitimately helpful. Most businesses that offer marketing services specifically in the crowdfunding industry do not offer useful services, instead services that include fake shares/likes/followers, copy and paste press releases, promotion to millions of fake Twitter followers, etc.
I know this probably seems hypocritical as I also offer marketing services but these people give myself a bad name and it is disappointing seeing more of these guys popping up every few weeks.
Kickstarter themselves do actively ban duplicate spamming accounts and everything but there is only so much that could be done. I am thinking they need to filter the names of these companies in private messages so that they get notified whenever someone sends a message that includes the word 'kickstartermarketer' or whatever the flagged business name is.
It can sometimes be worthwhile to look into who is sending the message as sometimes they can be a good business that is just starting and are trying to get the word out but I wouldn't count on it. Do your research, ask questions, and interact with crowdfunding related forums to get other peoples opinions on services and pricing before you go ahead.
All the best with your campaign!
