Reuters spam

I'm not sure wat the problem is, but it's starting to annoy me a little. A while ago I purchased the Reuters Vendor 2.1-something, now I'm getting spammed for version 3.0.

I've tried to discard, keep, mute to it, without any succes.. I've deleted all old and obsolete versions from inventory and trash, but still the spamming continues (4 times a day I think)

The object '[Reuters] Vendor' in Second Life

I've even contacted Reuters about this. No success yet. Any suggestions?
