i can undestand such the spammers like JOooOHN, who makes shit, but the thing is that his shit is funny!
but noone healthy person can like that google imagaz which sorted and shitty sized to 1920x696 by 10 years kids.
Unless the description of the map says "Haha, I'm spamming the WMDB!" there's no real concrete way to define it as spam. If there were, it'd be deleted; we can't ban people, though. Or at least I can't. Accounts can be deleted, but they could still upload maps as guests; I don't think we have an I.P. ban option.
stringking: I think there's an add-on for Firefox that allows you to alter the way pages are displayed client-side. Other than that there seems to be no way with the current interface.
Would be easier to add functionality for a filter of this kind to the server-side .php files, though ^^
There's a big link that says "Review" and lists the number of maps waiting to be reviewed in the top-right of the page for us. As soon as a map is submitted or the complain/suggest button is clicked, the map gets added to that list.
