Ive been trying to sell my processors for a while now i have 2 brand new i have tried to do so on ebay and mercari but there were problems they said my selling patterns changed and my accounts froze
Other than selling locally or on another site your best option would be to get in contact with ebay and see why you were suspended. Talk to a real person.
You may not want it, but people want protection which is what Ebay offers. If you are trying to sell it on here, I would not recommend anyone deal with you.
i've personally been in the same boat as you, had some high value components to sell but eBay wants to pull off as many delays and restrictions for inactivity but....
like the others have said, people will be much less likely to purchase something of high value and risk without such protections, no one in the right mind would avoid ebay and other online marketplaces to scour places like Facebook markets if they were looking for say an AMD Threadripper
