The spam is just noise like Kekistan's incessant frogposting on /po/ and /r9k/. It's a landing pad for KoG >>1478686
to report get and drawfags/art fags to post drawings/art! For most of /bant/'s history Cirno threads have been confined to one or two long-lasting threads which tended to last about half a week but ran into the issue of getting filled with off-topic spam: having them spread across 9 threads means that even if one of them is spammed by someone like >>1479137
, it's impossible for them to drag down an entire thread like it was previously!
For a more productive Cirno thread, visit the flag threads. Current new flag is a cool black/blue one.
