No pun intended...
It does seem similar to Winter, but that's never stopped anyone before (e.g. germ/microbe, halloween/halloween2, luck/patrick). You can probably squeeze out a few more cold, ice and arctic-related smileys, in 8 months time or so. And we have hugs to play with this time around too.
Perhaps we can reintroduce the freezeban idea, suggested here by @TrueRedDevil in 2013. Though I would adapt this idea slightly. Rather than preventing you from seeing the chat altogether (with a thick screen of frost), perhaps it could prevent you from tickling others, switching pools, checking your friends list, clicking your own name, etc. (with just a thin glaze of frost instead).
But thank you for contributing this freeze power idea! =)
