For me, seanblue’s userscript that shows how many leeches on my dashboard really helps.
There. 53 Leeches on Apprentice. 220 Leeches on Guru. 107 on Master. 58 on Enlightened. And prolly many more on Burn.
I use some methods that had been mentioned by 先輩たち here in this forum. I tried searching the exact links but I failed getting them back. So I think I’ll just rewrite it here.
I kill leeches by talking a lot about it. But this is not enough. I may still forget about them. I must actively kill them by writing them. Really pay attention to their composition and radical/kanji difference. And to their mnemonics, or could be my own mnemonics or mnemonics from communities.
I don’t only put them side by side as a pair passively but also actively. What I mean is, I don’t only use acm’s userscripts and see some of them listed there along with other similar kanji. I really put efforts to kill my leeches by writing them offline on piece of paper. Searching their refences on my Dictionaries. Searching for their thesaurus. Searching for their more context sentences. I use Dictionaries that Leebo had talked about on one of his YouTube vlogs.
I tagged Leebo here to let him know that I’m open to more of his suggestions on what to do to kill my leeches because I still feel an empty brain baby in Japanese. I edited it. No, I’m afraid I’ll disturb him if I tag him. So no I’ll probably ask him in another thread specifically when I can word what my questions are in hooman language.
My offline dictionaries.
My flow is usually like this: If I got recurring red, I take screenshot
And then I really pay attention to this pair of leeches. Thanks for ConfusionGuesser script on the top right. It makes my search easier.
And then I type on my Notes (Evernotes, could also Apple Notes). Like this
Then I generate their cards using Dictionaries feature on Kitsun. I once used Anki before getting used to Kitsun. I gave up on Anki because Anki is not for me. I highly respect anyone who can master Anki, like Hine sama and that penguin ava I don’t remember their username.
Then I do my WK LEECHES deck on Kitsun. Like this.
My current WK LEECHES deck on Kitsun.
Some of my leeches on my new WK LEECHES deck on Kitsun.

Question: How many leeches do you want to kill?
I once stopped learning lessons for 2 to 3 months just to focus on killing leeches when I was lvl 25. Of course, exposure helps but exposure usually doesn’t help me kill specific leeches. listening to J Drama. Seeing kanji in the wild on Japanese TV. I usually never forget whatever those Native Japanese said in the wild. But that’s more like an accidental. I got more leeches than those accidentals (coincidental? Sorry, my English).
I once had more than 250 leeches on my Guru. Then I got them down to 180. And now, you can look again at my dashboard above. I personally kill leeches not to 0. Around 150-180 is ok. Then I continue adding lessons again. And keep my numbers on my dashboard that make me feel comfortable. You could have these numbers different than mine.
I don’t only base on X Apprentice. Because usually Apprentices lower than 30 will make me bored. 600 or 700 Guru usually scares me. I could be comfortable on 50 - 130 Apprentice. And especially that userscript that seanblue created. I really pay attention on them. Not only in general bunny made on top like the one you got.
I may also want to use a specific tool, called I forgot what its name. It’s a beautiful graph, that if I click Apprentice 2, it’ll only show items that are in Apprentice 2 only. Etc. Because I forgot what that tool’s name is, I just use kind of manual tool but still useful. It’s wkstats the new one.
And repeat the process from my Notes to my SRS of choice 
again.
