After review, here's what I've observed from the clips and picture.
The first one is just chatting shit in OOC. Since you are making baseless claims that staff are abusing, don't be surprised that he comes back at you with the same energy. The first clip is invalid.
For the second clip (and third connected), there is no evidence to showcase that Brownie took your pots. The other clips are invalid.
Finally, the RDM against you is not appropriate, and we have addressed the issue with him.
