Not sure what you mean by cell but there's always bad things everywhere, especially in ecosystems that give you a lot of freedom's and new things to discover. This is one of those where we have people/community combat rather than, say at youtube, it's mostly bots/AI flagging content, giving out strikes, etc to accounts with little oversight.

Here we can talk things out and hopefully come to a solution, but it makes the things some times take way longer and be more demanding and time consuming, often because the abuser does not want to find a resolution. In that case the community has to protect what makes it work.
