The Financial Times is shutting down their Mastodon instance (alphaville.club).
Their reason? Security, liability, and cost.
With all due respect, I believe they went about their instance the wrong way:
1. Keep your instance moderated, you're less likely liable
2. Keep your instance closed to registrations, you're more secure
2. Keep your instance light, it's inexpensive
Also: Financial Times' site runs in WordPress. Why not use WordPress as an instance?
