as neochiny explained it was a bug that has been around in cloudflare services which all these bitcoin related sites use.

but it is strange that i have not yet received any email from any of the excahnges that i use and others are saying they have received them! i had to see it on somewhere else and then bitcointalk to go and change my things (it is worth mentioning my accounts are a couple of years old)

oh and also there is a topic about it if you want to read more:
