If the images get deleted automatically in code I dont see any reason for it to become a memory hog
The main argument I see for it is to protect new members, this category is unlikely to know where to find scripts or pick up this parricular one.
The reason to care about users getting scammed is that they were cheated out of "their" belongings, its reasonable for young, early teens and before, to not think about how likely they are to ve scammdd on their first duel when theyve never even heard of the forums
also itll take almost no work to code
