Roblox sent everyone the Egg Hunt message in their News page 3 times. One a day before the last two, and the last two at the same time. I believe the bot that sends the messages had an error in its system, causing the messages to repeat themselves over and over.
This has happened with past events and could effect future events with this glitch, so this issue might as well be fixed as soon as possible.
Could be an error, but if you look at the times they were two different days. The top two messages were sent at the same time which was most likely an accident but it just looks like a way for Roblox to send a reminder out about the event. Looks purposeful.
Since they are sticky and do not give the user any sort of notification, nor have read/unread state (that affects message count on the tab), there is no reason to send it multiple times and it is probably not intended.
You should file a new report for that, this one is about the “News” tab items being duplicated. That one seems like a different issue where the inbox notifications are sent multiple times.
