I replied the client asking about these foolish clause in the contract and he said he just wanted to filter out the potential developer and wanted to see who paid attention to the details and he will send me the revised version.

Now he replied to the same email(the email with previous contract) with new contract where line 53-75 replaced by a para which said I cannot disclose any of the info given by the client about the project. Now what yahoo(client)/gmail(me) did was, it nested the old contract inside the new one as it was reply to the thread by the client but while replying to the email for agreeing, I manually removed the nested part from the reply which had the old agreement and added this line "I accept the terms and conditions stated in this email and this email only.".

After this, the client said since you have agreed to the terms, you will have to buy a control panel access by paying him via paypal to which I disagreed post which he started threatening with legal consequences since I have signed the agreement. He kept threatening me by Odesk messages. The odesk message thread: http://i.imgur.com/yxgOXgB.png

I reported this to Odesk but I just got a reply from them asking for screenshot email where client was asking for money, I replied more than 10 hours ago and there has been no response from them.

Now my doubt is, Am I legally safe here or is this some noob online trying to con me?

also, He has my email id and basically anyone can get my complete address and phone number using my email id from whois databases since I purchased few domains with same id. Is it possible to get that data removed?

What should I do next?
