Should forums delete accounts that not active for a long period?

[Cpvr]

Still, I feel it's not a good idea to delete accounts because I know of many forum owners who prefer to sell the forum at a profit after some time and if they have more user accounts then they can accept a decent value of their forum

As a forum owner, I don’t believe in deleting accounts. I wouldn’t like if my account was deleted after years of building my account.
