Lots of people lost thousands from their lists and didn't get them restored. Contacting admins isn't going to do anything

They're currently not responding to emails because they are busy. Even if you contacted them, there is honestly nothing they can really do.
I get you. I never tagged anything and I went through the last 3 months of browser history alone and recovered ~300
Unfortunately, if you want your lists to be restored, at this rate you have to do it manually.
Also please, don't touch your lists. If you're recovering your lists do it off-site please.
i barely rated any mangas that ive read over the past 6ish years so i only had around 20 restored. Im missing multiple thousands... would it be worth the try to write the admins and if yes on what platform?
