Depop removing negative reviews?

i recently had an event where I purchased something for a good price, and I guess the seller had seller's remorse; cancelling the order and blocking me.

I heard about 1-2 star reviews being deleted due to retaliation. So I left a 3-star review with two sentences explaining that they told me they'll ship it out and blocked me. I guess Depop thinks that retaliation?? I don't know, but I know the seller contacted support and were able to succeed in removing the review

I hate that you aren't able to warn people about anything, like my experience with this seller was just swept under the rug. I hate that they are just able to get away with it
