not a clue, ignore it and move on - we used to get them too, keep writing good content -don't spam post this or you will get downvoted. You are gaining support keep posting

But I do not really understand it, that they do that without saying anything, it is incomprehensible, I am afraid that every time I publish they continue to give me the negative vote.

Also I have written to @ocd the reason and I did not get an answer, I will wait a few days to see if they answer me and then I will write something to see what happens, thank you very much for your support
