The posts and even comments on @FreedomConvoy have been targeted by these same downvoters.
It appears to also be about diminishing certain topics from the platform, such as the entire Freedom Convoy movement. There are several whales who do little more than look for such content to hide with their massive downvotes. This keeps Freedom Convoy off the trending and hot pages. There's a political agenda at play here and it's sad to see on the blockchain.
Edit: For example, this account's rep was 55 yesterday and is 53 today. It would only take a few more days (rep is exponential, like the Richter scale) to completely destroy the account and undo all payouts and visibility. This is a problem.
