If you have a twitter account check your permissions settings and enable login verification. Turkish hackers have brute force hacked third party apps with access to twitter accounts to spread political troll spam. They’ve done this to hundreds of accounts not in any way related to Turkey or the Netherlands. It looks like the main access was the third party app Tweet Counter (which needs permission to read and write from your twitter account to work), not actual Twitter passwords

This is a good reminder for regular security hygiene. Turn on two-step authentication. Go to settings and privacy / apps and review what you’ve given access to your account. Revoke any unnecessary permissions. Keep your passwords updated and don’t reuse passwords.
