If you really want to confirm then you can send them an email, but I hear they're not really responding to emails are they're busy
I can't find the links for more, but I have seen multiple posts where people have received a response from devs confirming this.
I also hear from others that they may still be recovering works though, so do what you wish with this information.
You've got a lot more works back than others because you actively rated stuff too.
I'm not sure why you'd want to delete but to each their own I guess
I'll just paste my usual shit here, you don't need to read it if you're decided

Cuz im still missing about 250 mangas and im missing every single of my comment i left after reading some mangas and if im being honest they were my fav part of this site and they aren't coming back. Also readding every manga manually will take a while and i see no point in doing that bc i wont know when i read them (also cant remember every single one that u read). So yeah ive lost motivation to read and stuff yk. Maybe wont make sense to you but thats just what im thinking rn. Am i giving the 365 buttons comment...
If it's your decision that's completely okay loves
I've already been responding to ts for 100 hours so if I sounded blunt asf in that response sorry
It'll be sad to see your history go, but if this is the push you need to move forward then I'm wishing you succeed in whatever next step you're taking!
(personally I would suggest just leaving your acc active but not visiting as much cause I'm a sentimental person who hates being rid of stuff, but again your choice <3 )
Everyone lost their lists even those that have been using this site for so many years. Re adding is a pain but you don't have to do that- maybe just start over i guess. I mean if you delete your account won't you start over anyway unless you're giving up reading entirely. It's really painful and I was so hurt too but what's happened has happened...

Ok so unmarked mangas and the comments also arent coming back? Thats 100% certain? I just wanna know bc i want to delete my account and i dont want to regret it after when i find out that they actually are coming back... So yeah
