Ah, spoiler wank.
Harry Potter spoilers ahead.

So, over in foundphotos, obvious troll ericseguy posts a HP spoiler in very large, scrolling font.

See it get the reaction he obviously wants. Only posted an hour ago, so still going very strong.

Anonymous posters in the comments mention he did this to other communities as well, but I haven't seen them. There may be more wank waiting out in the wings.

ETA: In case it wasn't obvious, there are also spoilers to be found now in the comments of this post. Spoiler virgins beware.
