Mud Flood content has been around at least for 2 years now. I was following this guy for awhile, well before Q came around. There's quite a bit of random topic's on this dude's channel. Some of it is click-bait to get new viewers. I will say that some of this guy's material does eerily mirror many of the Q topics. He made a number of videos about Trump & Putin vs. the Globalists.
The story behind the mud floods shouldn't be ignored, tho. There's a lot of shit that hasn't been accurately been presented to us. This is just another one of those things. It's worth investigating, IMHO. I found out some good info when I started digging.
