The reference to ice cream in the “We heart the Free Ice Cream” thread’s OP links to a General Moderation Thread post about a banned user not appreciating all the free flavors of ice cream offered on BoingBoing - a trope here on the BBS that is a reference to BoingBoing and the BBS being free. So the thread is, I would say, titled based on the trope, and a bit of a pun that incorporates a meta reference to the forum itself, though the author might disagree.
