Apology for the delay, but I'd like people to know that this is a poll conducted by Weekly Shonen Magazine on their 26th issue, and Magazine Special is the one that published the result. Basically, Mashima had drew twitter icons for 45 major characters of FT, and Shonen Magazine asked the readers to choose their top 3 from the list of 45. The list of characters, in their twitter icon form, can be seen here (credit to Umnei for finding the link to it).

Below is the printed location of where WSM asked the readers and the list of characters:
