Blurt had several issues but lack of downvoting was it's greatest strength, and it was almost spam free simply by emphasising the fee on each comment. It has mainly turned to shit because of some power crazed tosspot insiders ripping it off.
Looking at trending, I'd say most of the "top authors" are all part of insider the voting club, and there is far better content earning bugger all, so it would be no great loss - they are nothing special.
