 You're right—the block is not so effective when there's that much IP hopping.  I don't think I can issue a rangeblock without checking to see how much collateral damage there would be to non-vandal users in the range; someone like , who has checkuser privileges, might be a better person to ask. Or you could go to WP:ANI for potentially faster service. ) Thanks for keeping a lookout; some of the vandalism is quite subtle, so more difficult to notice.  (talk)(contribs) "
