 // When receiving a reaction note, look for the liked id and increase the
 // reaction counter in the note metadata database

-// TODO: I found some bugs when implementing this feature. If the same note id
-// is processed multiple times in the same ingestion block, then it will count
-// the like twice. This is because it hasn't been written to the DB yet and the
-// ingestor doesn't know about notes that are being processed at the same time.
-// One fix for this is to maintain a hashtable in the ingestor and make sure
-// the same note is not processed twice.
-// 
-// I'm not sure how common this would be, so I'm not going to worry about it
-// for now, but it's something to keep in mind.
