Thanks to diho, you can use ioclan.tk again! I know this is the moment you've all been waiting for
Apparently Dot TK first asks some money and then, when you're apparently not ready to pay some months (year?) later, it's available for free again. I tried registering, first it told me it couldn't confirm I'm not a robot (I checked in the mirror and, well, I see their point), then I hackishly transferred my session from private browsing to a normal browsing window but it gave me some vague but different error, then I tried the whole thing in a normal browsing window from the start and I got the same error message (they probably just hate Germans or something (I have a German IP address these days)), and then Diho tried to register it and it worked for him
Aaaaaaand now, writing this a few hours after the registration, they're having issues and a lot of .tk domains are down xD. Hopefully you can use it by the time you read this.
Surely somebody still reads this, right?
Right guys?
