Other People Identifying items?

Ok, i was browsing the service forums and noticed several people were identifying items for a price then giving it back. Why is it good for a person to do this? Does it give you a better chance of getting better mods on an item? (Note: I have searched and have been unable to find information on this)

The person paying to identify the items is seeking a title for XXX # of rare items identified.

They are willing to pay you to save them the time of collecting all those rare items themselves.

They are attempting to get the wisdom title for identifying gold items.

......right, i didnt read what they were saying correctly....thanks for the replies.
