Spam Group FaceTime Calls with over 32 members

Starting around 2 am this morning I began receiving group facetime calls from a mix of numbers in my contacts and random numbers I didn't have saved. Since then I've received about 7 more calls throughout the day. The calls only ring once or twice before ending. What's even more interesting is that, after going back through the numbers involved in the calls in the "recents" tab of the facetime app, there were more than the 32 total people involved with the highest being 59. The reason I think this happened is that every number was repeated once or twice. This is obviously pretty odd, and I would brush it off as spam or a prank but the fact that the same numbers were registered as being in the same call multiple times and that this caused there to be over the 32 person limit makes me think this is more than that. Anyone else have this issue or know anything about it?
