All presence on the keyservers says is, "if you have something to send
me, you may send it securely".  It is not a permission to send someone
email they'd prefer to avoid.

Further, the conduct the OP is talking about amounts to dragooning
someone into helping you without first asking them whether they're
willing to help you.
