For a starter, I hate been redirected out of forum to go read some article, if you're the original owner of article then post then on forum and you can add a source link at the end for reference purpose or indicate you're the original owner of article to avoid been accused of plagiarism.
In addition: There's a disadvantage I have noticed in the past project that carryout their crowdfunding through IEO which is very disturbing. The whales are manipulating the sales, they buy all the token in matter of sec/mins leaving the average investor with no token to buy which is bad because this guy's can easily manipulate the price of this coins/tokens when they hit the market. Exchange need to find solution to this issue which could be solved by putting buy limits on each account.
Having the same feeling too on where posting up some links which would redirected into other sites do really sucks.
IEO is the changed-faced of ICO yet it do add up some security but there would always be a disadvantage in exchange which is manipulation for those financially capable to
buy out huge volumes of tokens for the sake of profiting benefit.
