Every week there's one or two Touhou works out of dozens of other good work. If that's "being presented to you constantly" then like 20 other franchises also meet that criteria. I don't keep up with those things but I don't go into the comments and say "I blacklist xyz franchise because I'm reminded it exists every week". That's just inciting conflict.
In fact, those images tend to become gateways to new franchises since I get interested in characters or pairings I like and I look it up.
