Ebay ebay.com ebay.ca Robbed me of my personal information permanently San Jose California

I created my first account with eBay two days ago. Yesterday, I was informed my account was suspended indefinitely. I first thought it was a phishing email cuz I've done nothing with my eBay account other than posting one single post to sell a pair of speakers (for $10). I called the customer service, and they said my account was suspended permanently because:

1) My business model is different from theirs. They refused to elaborate on how they define a business model, how they evaluate one, and what the differences are, etc., stating it's proprietary information (which excuses their violation of PIPEDA 4.8.1). Also avoided to explain why difference in business model is a valid reason for banning accounts.

2) My account activity poses security risk to the eBay comminity. The previous reason might make slight sense to some, but this one is simply absurd. my only account activity is to create one single post selling $10 item, and somehow they see a security risk in this account. Again they refused to tell what the security risks are and how they evaluate accounts, saying this is to prevent future accounts being opened with newly aquired tricks (which I have zero interest in).

Although those reasons seem to come from nowhere, I'm 100% fine with them since I have no desire to do business with a company that has such level of arrogance. What comes next shocks me however: they outright refused to close my account, or delete my personal information from their database!

"That can't be legal!", I thought, personal informations are protected under PIPEDA, user can withdraw consent of giving their information at any time, and any data that are no longer relevant to business should be destroyed (PIPEDA 4.3.8 and 4.5.3). eBay, who I thought to be a distinguished enterprise but turned out to be the biggest scam, explained that because my account is suspended (implying bad intention behind the account), obviously they need to retain it for security reason (again excused from violating PIPEDA).

Now my personal information will be, permanently, retained on eBay and any third party they work with, forever exposed to hacker attacks and security risks (which happens a lot with eBay). For all I know eBay could randomly have new users banned, and considering the amount of new accounts created every year, they can collect considerable amount of information for free, without providing any service in return. Please think twice before you register as eBay user, EBAY CAN PERMANENTLY RETAIN YOUR PERSONAL INFORMATION without suffering any legal consequences.
