Do you know if they are currently doing any big promotions except for these pretty random advertisements?
Nope, i think i wont be really effective since their platform is still not fully developed according to the roadmap.
Other projects are doing promotions without any platform at all, so why shouldn't it be effective? Especially now, when they could distinguish themselves from facebook and take advantage of the negative attitude towards facebook..
If you see the roadmap, they already did the ICO marketing which spreading the word about the concept of this project in Q3 2017.
And now if they want to do a big promotion where they will "promote their project/product", i think it will be better to wait until its fully developed.
I think they should intensify their marketing campaign during the ICO to capture as many investors as possible.
