Dlsite has hidden several works from oversea buyers, and as result you can not access them even if you have bought them yourselves unless you have Japan IP.
As such, not recommend buying from Dlsite. If you still want to purchase, make sure to save them to your hardware/cloud or upload them so you can still access what you bought in the future.
I won't blame DL if they give a satisfactory reimbursement for the overseas buyers affected by this new policy, or at least give a warning so they can download their purchased items. Instead they just pull the plug one random day, and suddenly a good chunk of my library gets wiped. If I didn't know that these items are still available behind Japan IP (thanks to our forum), then it could be 10.000+ yen waste for a bunch of dead links.
Also, I have absolutely no idea why some works are purged. The forum said the common trouble-maker like lolicon or shotacon got the plug, but why did these two Horikawa Gorou works get axed too? Anyway, I take no chance with this, so I will upload my remaining dlsite library here soon..
