Ah, that’s a good callout. Like @Megumin said I do have a variety of redirects, but I guess somehow I missed that one. Should update.
Ok! Well let me know if you’re able to log a false positive, would really help. I’m not entirely sure why I’ve gotten a batch of false positives recently… I haven’t received any feedback that i’m doing anything incorrectly. The only valid issue I’ve found is with regards to email links, which @cat noted, but that should be fixed.
That is intentional, so not a bug.
That’s a very valid opinion and I think ideally it’d work similar to that… essentially I think we should generate personal difficulty rankings and combine each users rankings together to form the community’s. However, in the current system, your proposal would give one user too much power to adjust the rating if they have an outlier opinion. This is pretty similar to the discussions we’ve had before, such as Drag & drop difficulty grading - #2 by GrumpyPanda and the linked comments there from this thread.
You’re of course welcome to add a product request and we could discuss more there
