I remember another member while searching who is even more of a noted critical support of Gapcoin.  He payed 1 Bitcoin to list Gapcoin onto Cryptopia.co.nz after Poloniex de-listed gapcoin, but kept Riecoin listed.  After this failed assualt, as Riecoin distribution is bad Poloniex saw the "Math Coin" is no longer making money so they eventually de-listed Riecoin also.  Primecoin was listed on Poloniex also I think?   I don't know anything other than that which one got de-listed first Riecoin or Primecoin?
