One mod’ said it was one person doing it last time. Might be more now, seeing how large this recent flood was.
 
I feel they’re doing it, because they’re upset that the Sanik-haters here were downvoting & leaving rude remarks on even the decent Sonic pics. Meanwhile, the Sonic upload floods are encouraging the haters to do it more. So it a vicious back-and-fourth cycle between the uploaders, and the haters.
 
EDIT: We have confirmation it’s that one guy doing the flood. >>1266717 I’m a li’l impressed one person can find & upload that many pics.

@Beau Skunky  
only the mods will know who’s at fault for the sonic floods. all we’ll ever know is that it’s “Background Pony #XXXX”

@Aurora  
I have nothing against the ‘ship personally, (after all, if people like shipping Rainbow Dash with all of her friends, Spike, Discord, Gilda, ect. they’re really in no place to tell people what they “can’t ship”) and I actually do like the Sonic series, but seriously 90 Sonic uploads in a day is too much. Who is doing these Sonic floods?

@Axel_Changeling  
it’s not that they’re against son-dash as much as they’re against the bad art and sudden spam about once a month.

Okay, it’s become quite clear to me that based on all the downvotes all the Sonic and Rainbow Dash images have; fans must have a seething hatred for Son-dash XD.
