Can someone offer insight into the "hugs" I've been receiving as PMs?

Yesterday, several Fluther members sent me a private message that simply said, ”Hugs!!!”

I had no idea what this could possibly be about, so I wrote back to them asking to what this was referring, and they have not responded. I looked through all recent Fluther threads and could not find something I said that could have warranted the need for hugging. I am not sure if these hugs were only sent to me or if they were sent to multiple members. I am completely unclear as to the meaning of these hugs.

If you have any information regarding these PM hugs, please provide. Thanks!
