Take a look at this:I thought that a user could only vote once.

Thanks WE – I’ve seen this once or twice before, although pretty rarely. I think that this may happen when someone has cleared their cookies/cache, since I believe the tool keeps articles you’ve already voted on out of your queue that way. But I’m not positive - I’ll ask Souphead about it, and advise them (and anyone!) to skip if they already see their own vote on an article. I’ll touch base with the engineers about it at some point too and see if there’s any fix – but a good rule of thumb in the meantime would just be to skip any articles you’ve already voted on. I’ll let Soup know. Thanks!
