Spambot friendings

Okay, gang, there are some new spambots running around friending people randomly. If you get friended by any of the following, don't friend them back:

ojugpodpod
niephajv
iaminci
ijpudob
domiomvz

Thanks to trippiekat and naetara for the info on the first four; the fifth one friended a couple of people I know.
