I've been getting a lot of e-mail spam since our switch over here. This happened to be before when I joined another VBulletin message board. Eventually they went away.
Its a pain in the ass but after deactivating my acct. I went through and blocked each web address. I did this before the new board was up and havent seen an increase since being here. Hope it gets better for you- I hate spam!!!I had a Facebook account, but I deactivated it last week, but still getting spam.
