I wouldn't call this a scam, but it was really funny in my opinion. So, there was one time Aurora wanted me to sent a present to Rudy, and in the present was a neutral wall. He said he was okay with it, but really didn't like it. So, when I told Aurora about it, she was like "eventually he will like it" (this is in my own words/not sure what she said exactly).
Later in the day, Rudy pinged me and gave me a neutral wall! Then, Bob wanted my neutral wall and he traded me for an item. When my sister got on, Bob gave her a neutral wall. Eventually then, Pekoe wanted the neutral wall and it wasn't until days later, my other player got a neutral wall from her.
Sorry if this is pretty lengthy but basically the neutral wall passed on into a cycle. Aurora➝Rudy➝Me➝Bob➝my sister➝Pekoe➝my other player.
This is another that I kind of thought was insane but felt was worth it.
I was going to sell my bugs when I got back from the island. Hans pinged me and wanted my golden stag. I was like "NO WAY, you're not taking my golden stag." But I couldn't deny his offer after hearing how much he was paying for my golden stag.
