Based on the screenshots, i feel like they were just exploring around your decks. At first I thought you meant comment spams. Has they harass or send any hates comment towards you?
Quick info, you can also turn off the specific notification if yo don't want these to notify you! just go to ur pfp section and click settings that is next to "notification" and turn off "someone played your decks" or wtv it says. Hope this make you feel better :3
Im so sorry if i did annoyed you but I agreed with you.i was so happy that i got 25 on my profile and then when i looked it was just the same people -.
