Certainly, recently a colleague on the blockchain gave me a shower of negative votes because I post a lot and he suspected it was spam, but it turns out that when I asked him if it was something that I had done wrong, he confessed that he had not read my publications nor had he reviewed the content of my post, he simply thought that since I published a lot it must be spam and deserved to be punished with negative votes ... well, it was good that we could clarify it and that he saw that I had no repeated content in my publications, Besides, I admit that I annoyed him a bit to remove the negative votes, after enduring my annoyance for three days and seeing that he had really been wrong, he was very kind and withdrew the negative votes.
I really hope that in the future you read the publications before giving negative votes, because it is very hurtful that they give negative votes to the publications for free, at least I would like it to have a good reason.
