bitcointak is a pretty good place to reply to promote the ICO project that you follow.
social media is also the alternative to promote the ICO like Facebook, Twitter, Linkedin, Instagram, telegram
but bitcointalk is the best.
many of them are often asked, where is the best place to promote the ICO?
I suggest they try visiting bitcointalk, maybe you could find the answer of yours in there.
but I can recommend 1 ico
