(11,785 posts)Yes, it is a good function to consider the input of other DUers. Yes, it is worthwhile to consider that someone might be a returnee of a known frequent flyer. It is not uncommon for us to ask for an IP check in those cases, even if there are "no hiddens, no disruptions". That's not just for the particular troll suspected in this case; it's for all of our regulars.
It is not that unusual for a MIRTer to be well-versed in recognizing a particular troll, so I'm not sure why you find the idea that occasional tips are all coming from the same DUer to be so ominous. This isn't the only troll we get tips about, and I wouldn't be surprised if some of our other tips are also coming from a single ex-MIRTer or former mod who's good at recognizing a particular troll.
If we get a bad tip, well-meant or otherwise, and an IP check comes back with no match, that's the end of it unless and until there's actively trolly behavior.
