In the community section of Katy Groves' YT channel Groves announces in one of her posts on there that she will be releasing a playlist of videos that resemble Mkultra trigger tapes; she's doing this so that people who want to learn more about them can get a sense of what they tend to be like.

Here is a list of YT channels mentioned in the OP and in the comments that post such videos:

KrainaGryzbowTV

In KrainaGryzbowTV's featured channels I found this channel having similar material: https://www.youtube.com/channel/UCnmPchC6HI70rF65bC-uffg

I also found links to other related pages, like bancamp and other merch pages; feel free to dig even deeper and share your findings.

KrainaGryzbowTV and WiktorStribog are both Polish; perhaps these names could be leads that may expose the Polish connection to the worldwide elite child trafficking rings and mind control programs.

Besides that, when browsing these videos, be careful not to let them affect you negatively; if you're up to the challenge, please take note of your experiences and observations of symbolism and psychological manipulation and share them so we may potentially be able to identify commonalities between this material and the way elitists try to engage affairs in the MSM and spot more potential predators and leads.
