Forum:Deleting talk pages

So for the last, I don't know - year? - IP talk pages have been deleted when the associated IP is perceived to be vandalizing. I would like to know what the hell that's supposed to accomplish. Is it to get rid of the welcome message? Because their edits aren't actually welcome? Deleting their talk page just causes them to receive another welcome message the next time they edit, repeating the process. And, ignoring the occasional non-welcome message that's actually deleted (as in, a user is actually trying to have a conversation with the IP), deleting the talk page does not double as a warning to the user, which I assume is to be a secondary purpose.

Can we stop doing this, or is there some other benefit I'm not seeing? ~SnapperTo 05:50, April 11, 2011 (UTC)
