I generally agree with psa's assessment here. One more note:

A genuine subscription request, if accepted, gives the requester access to your
full presence (<show/> and <status/>, not just "available"), and any pubsub
nodes that have the "normal" PEP access control level (geolocation, etc.).
None of those were actually necessary for the session they wanted to establish
with you (e.g. a Jingle call).
