Who would benefit from posting their product to 125 websites except spammers and growth hackers?
b) I don't have to promote to all 125 sites, I can be more targeted.
c) You're automatically treating growth hacking as spam. Growth Hacking is a common promotion process - the issue is how it is accomplished. Promoting on lists - good. Making fake websites with fake articles / reviews - not so good. Paying bots to upvote - bad.
