I'll try to be brief as possible but I have a few questions that might be worded a bit excessively so they're not unclear. (Sorry in advance for the wall of text...)

- Would it be possible to create a decision that greatly reduces worthless guest arrivals at all times, or if necessary later on, just locks down completely the constant stream of single-county claimants on lands my vassals already control?

-- Getting 3-4 "Gimme a year / GTFO " interruptions twice a month in the late game is making CK3 a daily migraine dispenser. It would be ideal to have a decisions prompt series thru which we could be spelling out as needed at any given time what the game should restrict coming to your court, given the fact 99% of guests would have already gotten those titles if they weren't garbage-stat scheme-obsessed deviants of no use to their own realm.

--- Would it be possible to have a Purge Guests Under: x, y, z Parameters decision, thus allowing you to set minimum requirements for stats or traits and just have the game auto-prune the lowborn or evil/craven/lazy 0/5/3/7/2 stat guests with honor -1000 greed 500 hostility 10M AI motivations. No medieval lord would ever welcome them if they're guaranteed to scheme against, seduce, dig up secrets on, and blackmail the people you actually do want in court, since they/re all joining each others' plots immediately. Turds of a feather, etc. Most days I spend as much time pausing and scrolling through courtiers dismissing sociopaths and lover's pox enthusiasts than I do playing in the late game.

---- And is there any way to code in some common sense to dynasty members that in RL would almost inherently understand their place in the world and their responsibilities as educated divine right rulers/heirs, so as to be more realistically resistant to seduction - like if they have a child up for inheritance or their spouse is already their lover/friend, add on a 50% extra resistance to seduction, and 100% resistance if their would-be seducers are inbred diseased covetous villains, for example, 'cause one of those genuinely sniped my best heir in 250 years out of their marriage, their religion, dumped a bastage into my bloodline, and eventually they died a pox stricken excommunicated lunatic in their spouse's prison.How a temperate midas touched character would make such a massive mistake seems like some classic Paradox artificial difficulty bypassing your smart plays to keep you from snowballing the AI.

It's srsly just murder on the immersion as is, since my hard-earned genius + herculean offspring are apparently too weak willed/stoopid to resist the dozens of 70 year old, disfigured, syphilitic evil blackguards the game dumps (many of them repeatedly) into my court, 'cause the AI must assume I always wanna go to war with my carefully built and maintained warmonger monster vassals (kept just strong enough to spread my empire borders without eating me in the process) so as to press that impossible-to-ditch character's solitary weak claim on a lvl 1 castle holding in one of my bloodthirsty vassals' capital county....

Again, sorry for the length of this post. But thanks so much regardless for all the hard work filling in for the devs at the moment in the absence of any hotfixes or patches to get this madness under control. :)
