EDIT
Regarding them only doing it more if you leave a low-scoring review:

^^Case in point.
Yes, that is the level they'll go to just for more attention. : /

Point E of the review guidelines:
"Do not use reviews to express your feelings that the entry should be BLAMMED. If you post "BLAM this" or something similar you will be banned."
Ergo, the mod that saw it was actually being lenient on you by just deleting the review and not banning you for it too.
In future, if you see a flash that was obviously made just to annoy people, don't review it. It only makes them do it more, simply for the attention. If you really feel the need to do something, vote 0 and move on; its the best anyone can do with crap like that.
