My account was banned by a platform

Step-by-step legal guidance hasn't been verified in Suomi yet, so it's shown in English below. The interface is in Suomi.

Did the platform give you a notice explaining the decision (a "statement of reasons")?
Yes, I got a notice
What's the problem with the decision?
The notice doesn't actually explain anything

Article 17(3) sets exactly what a valid notice must contain: the restriction applied, the facts, whether it was automated, the legal or contractual ground, and your appeal options. "You violated our community guidelines" with no specific clause does not meet that bar — check your notice against the ban notice checker on this portal.

File an internal complaint (Art. 20) pointing out precisely which Article 17(3) elements are missing. If the platform doesn't fix it, that incomplete notice is concrete material for a complaint to your Digital Services Coordinator (Art. 53).
