Is (Icelandic) vandalism

@Snævar: OK, fair enough. But have you tried talking to him to tell about the problem? I can't see anything in the user talk page, but maybe you have some other communication channels. In any case I'm hesitant to call it vandalism, it seems more a case of not being careful enough. If you want I could post something on his talk page, but it might be better if you do it since you know the specific issues much better than I do, obviously.
