Hey guys,
Is there any plug-in or any method at all I can use to identify comments that've been posted under different names but the same IP?
I've just launched a small competition on my WordPress site, and the entry requirements are simply that you leave a comment on a particular site.
The problem is that some people could potentially be spamming entries under different names, and verifying each name manually would be nightmarish as the competition already has over 1000 entries after just a day.
I don't mind putting some work into it, because any technique for making it a bit easier is a damn sight easier than doing it all manually.
