Yeah, I think a disagree button is unecessary and unhelpful.
BUT the way the two optionsof disagreement are presented are not very sensible to me?
Why is there the green option?
I do not understand it; as far as I can see, it does not change the CID, so is it not just spamming the activity field?
I always choose the orange one when I find something I cannot ID to species; insofar there is an actual lack of evidence. If I cannot tell there is a lack pf evidence (due to not being too familiar with the group, is it not better to leave it).
Hard disagree in forcing IDer to provide explanation when disagreeing every time.
I do not do it and will not do it.
Because in 95% percent of cases I get no response in any way. Why would I waste my time writing my arguments, if it will be ignored?
If you want to learn, I think a modicum of effort, like asking, is not too much.
I am happy to answer why I think so if I am asked!
However I do think if you make an ID on a research grade that makes it not so anymore; it is fair to provide an explanantion.
