'Verbieten' (to forbid) is an inseparable verb. The prefix 'ver-' remains firmly attached to the verb 'bieten' in all sentence forms and is not stressed.

The house rules forbid loud music after 10 p.m.
The verb 'verbieten' (to forbid) needs a person in the dative (to whom is something forbidden?) and a thing in the accusative (what is forbidden?). Alternatively, it is followed by an infinitive clause with 'zu'.

The prefix 'ver-' reverses the meaning of the base verb 'bieten' (to offer, to provide). To forbid something therefore means not to allow it.

Parking is strictly forbidden here.
In the reflexive form 'sich etwas verbieten' (to forbid oneself something), the action refers back to the person themselves. The reflexive pronoun is in the dative.

to block / to ban
Verbieten means generally that an action or participation is not allowed. Sperren, when used for people, typically refers to a specific exclusion measure, often as a punishment and for a set period. That is why sperren is especially appropriate for a time-limited ban from a competition.
