Conceptually, is there scope to have a global abuse filter? XWiki we are seeing bots appearing and dropping accounts with one-time spam, and then move on. We can see it through a number of sites, it is not high intensity, but regularly there. At this moment, due to the nature of the bot and a simplicity to its account names we can minimise aspects where we see it, the problem is we won't see it all. Currently AbuseFilter does allow a means to identify accounts, though that is a wiki by wiki approach, so the obvious question is there the scope for global AbuseFilter, even in some limited format. Thanks.
