Is it illegal to write at someone else's door?

Writing in front of someone else's house, if civilized and legal, is not a criminal offence, but it may be a civil infringement or administrative violation. It is suggested that the owner's consent should be obtained before writing, such as advertising language and various publicity slogans that are often seen in towns and villages now. If it is in a city community, the entrance of the community is generally shared by all owners, so the proposal is not written at all, which may also damage the city appearance. It depends on what you write on someone else's door. If the circumstances are minor, it is against morality. If writing insults or slanders them, if the circumstances are serious and affect others, it will violate the regulations on public security management and be punished by public security management.

The consequences of writing at someone else's door:

According to the relevant laws and regulations, if you write at someone else's door, the other party may demand to bear the corresponding tort liability consequences. Legal means can be used, such as negotiation, asking a lawyer to send a power of attorney, and bringing a lawsuit. And should not be carried out by illegal means, otherwise it should bear other corresponding legal responsibilities. The other party may demand to stop the infringement, restore the original state (remove the writing marks), compensate for the losses, etc.
