I know I have seen your research on many places without proper credit for your photos and research. Not only does not acknowledging you reflect on the site or account, but subsequent people who use that are not aware that you were the source of the information and it perpetuates a vicious system in which your hard work is ignored.
An example is your picture of Mrs Greville wearing the pearl earrings, which I came across on Pinterest in 2019, over a year after I had written my article on the earrings, and was not aware that you were the source of until seeing your post today (possibly because the original post on RJWMB is no longer active).
This is one of the reasons I am so hesitant to publicly share my own research until I publish an article on it, and even then I find recognized ‘experts’ taking the information and images and passing them off as their own, not replying to messages and even deleting comments that call them out. However, at the same time many people and accounts do acknowledge and rectify their mistakes when it is pointed out, saying they were not even aware of their error until it was brought to their attention.
