Tracking tips is a bit harder than most information. Since tips can be given on old posts. And it is a separate API by PeakD to query how much tip a post got.
Should it check just your past posts in 7/30 days. Should it check all of your posts? There is a big design consideration for it.
In blockchain level a tip is no different than a normal transfer.
