Ignore the trolls. Also, if they are upset with you they should focus their vitriol on me. I block nearly all of BRICS especially Brazil as most are hard wired to not follow even the simplest of rules, most data-centers, some VPN's based on MSS, posting from cell phones and much more. I am always happy to give people the satisfaction of down-voting me since I use uBlock to hide karma.

In ublock -> my filters
