Unless anyone knows another reason for this impressive increase in comments? Seems to roughly coincide with Sync launching. If thats the case, just goes to show the importance of good third party apps.

EDIT: Looks like a confusingly labeled graph and I think this is total comments. I have no idea why that spike could exist though.
That's not the number of daily comments, it's the total number of comments, by day.
So on day X there were totally Y comments on Lemmy.
The big jump is probably related to some instance adding a bot that copies content e.g. from Reddit.
