Good evening. I hope I'm posting in the right forum. I was recently changing my avatar on the site, and went to go treat or treat. I got tricked, and when I went to my inventory, I noticed an item I never bought/received in there: . I feel like this may be a glitch? Should I delete it?

No, its probably not a glitch. There are a couple of random events that could have happened that you failed to notice.

I believe that if you're ever concerned about where an item came from, you can file a ticket and a staff member can see some kind of log that shows where it came from.

But in this case I'm thinking it's probably the random event where a random minion "follows you home".
