Chaos-sama's Things

Of course, like your average bl (and manga obsessed in general) psycho, I have over 800 "have read" bookmarks, over 150 "reading" bookmarked series and my "to read" is simply... ungodly long. I know the whole km site shenanigan is same ol same old, people get scared it died forever, it's just under another country code, all is well. But with actual new legislation coming into action in 2021 in Japan... should I just be cautious?
I mean you never know, right? Or should I just go with it and trust that this site is probably (and will keep being) just better than km and it won't just let us down out of the blue?
Opinions? Suggestions? All appreciated, thanks.
Note: I'd have to manually mark down the chapter at witch I'm left with each manga in my "reading" & "have read folders" and that's why idk what's worse, potentially losing those bookmarks with nothing saved or perhaps taking the hours to make a list of everything that's in the end of no use at all.
Thanks in advance, y'all. ヾ(☆▽☆)
