Not everyone is savvy enough to do it, even though the process has been simplified with many hosting providers providing preconfigured VPN servers.

And it doesn't anonymize you that well. When you post a message that draws the attention of law enforcement, the IP will lead them to a VPN provider that hopefully doesn't keep any logs.

But if it leads them to a specific server, the hosting provider will disclose your account and payment data, since it is linked to your private server. Unless they accept fully pseudonymous accounts and let you pay for your VPS in cash, Monero or tumbled Bitcoins, finding you is much easier now.
