All repeatable badges have now a field - badgeLimitCount: 250. And it's showed in some badges' descriptions as Limit 250.
It looks like a test value, because for some badges, like a New Year, it doesn't make any sense. But going into just limiting badges count doesn't look like a good idea. I would rather make all common badges repeatable without limits, but with separate counters: global and monthly. Global would be like collecting all badges, and monthly how active user was during month.
