When someone disagrees with something that someone else says or does, they might try to stop them from talking about it or doing it. Sometimes, they might even take that person to court and sue them for something. If that person knows they didn't do anything wrong, they might be scared to speak up about it because they don't want to get in trouble or have to pay a lot of money. This is where "strategic lawsuit against public participation" (SLAPP) comes in.
A SLAPP is a mean thing that can happen when someone tries to use the court to stop someone else from speaking up about something. It's like when someone is playing a game and they don't like that someone else is winning, so they change the rules of the game. The person who is winning might be scared to keep playing because they don't want to get in trouble or lose the game. It's not fair.
In a SLAPP, someone might sue another person or group of people for saying something or doing something that they don't like, even if those people didn't do anything wrong. If the people being sued are scared to speak up, then they might stop talking about the thing that the person suing them doesn't like. This is bad because it can stop people from having important conversations and sharing their opinions.
Luckily, some places have laws to protect people from SLAPPs. These laws say that it's not okay to take someone to court just because you don't like what they're saying or doing. If someone tries to start a SLAPP, the court might say that it's not allowed and the person who started it might get in trouble instead.
