Have you commented or messaged them, asking for a reason for any of their mis-IDs? Perhaps also tell them that iNat observations may be used in actual scientific studies and that the identifiers are volunteers with limited time, so intentional mis-IDs are quite annoying.
If they don’t respond and don’t change their behaviour, you should flag their problematic IDs, so that curators can have a look. Adding misidentifications on purpose violates the iNat guidelines.
P.S.:
Though it is still on iNat, T. officinale is no longer an accepted species (according to POWO) and it’s probably best to leave observations of dandelions at genus for now, unless you’re one of the few who can ID them further (I tried, I can’t. Haha). The species has been split into dozens of micro-species that are almost always impossible to tell apart on iNat. @comradejon made a great post about this on here: https://forum.inaturalist.org/t/my-dandelion-manifesto/49999
