I posted a similar question to the Q&A yesterday:

Assuming it was possible, without violating G32 (or other rules), can an alliance put a tube on an opponents Rack?

(no answer yet)

G39 only applies if there is another tube on the rack. Whether you are preventing them from getting a logo or trying to increase your rank score, it isn't clearly stated in the rules. Agreed that it is very technically challenging, but crazier things have been done *ahem 469*.
