Yes, it started 2 weeks ago .... Not all, there are still 3 from the channel GMM.
Gone forever, I doubt Viki will have any more unlicensed lakorns..... I am just worried they may do the same for the C-dramas.

Except for a few, they all are available somewhere else...Check
-- Jasmine Lakorns
-- alwaysmeena

EDIT:
Also these sites now have lakorns, generally, a small selection, but caries:
-- DramaCool ...Dramanice ... KissAsian
-- Doramax264
They did the same with some CHdramas T.T 
Thanks for the recs Neyjour!
You're welcome! :)
They also did it at Dailymotion and I heard YT channels like AndrewGreagsonFC will be removing their lakorns.
---> An all out attack on us lakorn fans :((

Viki is aiming to have have more licensed channels so they can have more paid membership.

Luckily, I already suspected they will be doing that w/ Chinese dramas, so I downloaded Too Late to Say I Love You before it disappears! .... I better start watching the ones not available anywhere else, before they disappear also.
If they really licensed more dramas besides Korean ones I wouldn't be so sad because of that. I'm more than willing to pay that little sum each month, but I'm afraid that this won't accommodate for all the fan channels, even if they did license a bit more :(
I don't mind either ... I discontinued my Premium membership at Dramafever b/c they only had K-dramas .... and if it is a choice, I would much rather pay Viki than DF.... DF has too many issues.

Let's hope they will finally get Lakorn licenses... But by removing the videos 1st, a lot of subbing has been wasted :(
