they will ask secret question/ first and last name. I assume previous owner already reset it/ or tell you the details. hopefully you not bought botter account

different user uses different machine
the reason they suspended you is to avoid account hack
the info blizzard ask is the info from the account profile as created by the forumer

last time i bought, i need to fill out a form and photocopy ic from both party in order to exchange.

Nonono, what Sabenarian means is the account you bought is previously used by the ex-owner for botting; and got caught; banned; so he/she sell off the account..

Hopefully it's not

sorry for my confusing post above bro. Hope this link can help: https://forum.lowyat.net/topic/2354245

I am very sorry to inform you that , blizzard does not support account trading in anyway .
They are unlikely to assist you with anything once you told them you " bought " your account from someone else .

It is against the blizzard policy to trade account individually .

Buying an account from another forum guy is never safe anyway . You might as well be off to get another completely new copy of the game .

U should "tipu" blizzard a bit, said you account suddenly have problem w/o mentioning u bought this account form fren. Actually original owner should know this by resetting e-mail to your email, clear autheticator, changing secret question etc..

also need to change phone no. to yours.. D3 will pop-up secret question if it detect something unusual like u login on different PC..

I mayself login on multiple PCs for my account, home pc (2), laptop, Office PC.. no problem as long as i know the secret question.

If you bought the game from forummer, this means the said CD key already used to create / attached to a Battlenet account.

If blizzard asking for identification documents, you need to provide the ID that matched the previously registered information. E.g. If Mr. A created the battlenet account using his name and so on, you make sure Mr. A sent in his IC and not yours as this will led to permanent ban during buying / selling accounts which is prohibited by Blizzard.

My advice to us is ask the seller to do the necessary to unlock before sending it back to you or he willingly to scan his IC and driving license to you. Or you have all the rights to ask for refund. You bought items that cant be used.

Like I mention above, u can use different PCs to login to D3. I suggest u to enable authenticator for your account.
btw, may I know why u bought this used account? cheaper (new one also damn cheap now), high Paragon account or lot of gold inside it?

you can buy key from blizzard to create b.net account..then copy installation folder form fren.. just need download small update time to time..

then no choice to download it yourself   I myself download the installer using my office internet 2Mb/s. Then copied it to my home PC to play

Never tell them you buy already used diablo account, character farming is illegal and they can ban you !!!

my EXP:

I wrote an online form, post to blizzard support team, mentioning that i ask someone to buy Diablo for me and he helped me to set up a battle.net account

blizzard told me the battle.net account has been active for several years (opps, i sweat a bit)
blizzard team doesn't offer direct help, instead they gave me a form, telling me that if i were to take an account from my guardian, i need to provide both our IC and send to them digitally
Of course that wasn't my case, but i took that as a HINT, using the excuse they provide and give them my full detail plus the original owner's
(although if really look into IC, i am 10 years older than my "Guardian", opps... sweat again)

the pdf form i fill was provided by blizzard.

and then.... they unlocked the account, and i quickly bind the account using my mobile authenticator.
i admit i am very lucky in this case, at that time Diablo 3 majority still stuck in Inferno Act 2.
