I don't like how they promote this site/project either but there are some important points that I think worth to respond from timerland.
1. Maybe the 'exchanges' is just a list of exchanges where people can trade the tokens, I've seen this practice on several projects and as long as they don't lie that they're actually listed on that exchanges, I think that's fine. AELF is in fact listed on those exchanges.
https://www.coingecko.com/en/coins/aelf/trading_exchanges2. Wdym by 'acknowledging'? Putting this project on their LinkedIn CV? I think some advisors might not update their CV regularly, best to ask them directly for proper DD.
On the other hand, is there no dapps on Aelf atm so they need to promote their blockchain?
