Is the unsubscribe from RSU thread fishy?

For some reason, the post by steve about asking how to unsubscribe from RSU seems fishy, is there anything bad that can
occur from answering that thread?

Usually the spam has the bold email address as the id. Just my
paranoid two cents. Just seems wierd, to me, that’s all.

I know why would anyone not want to get stuff from RSU?
