How can I delete all PDA accounts for my program (anchor)?
Here's an example from my own code, closing my Counts PDA:
#[derive(Accounts)]
#[instruction(countsbump: u8)]
pub struct CloseCounts<'info> {
#[account(mut)]
pub user: Signer<'info>,

What stops malicious clients from using PDAs in a series of CPIs with anchor?

So let's say PDAaUW is derived from ProgramA and a user wallet's public key. … There might be another PDA, let's call it PDAbUW, which derived from ProgramB and some user wallet's seed. Then ONLY ProgramB can access PDAb for writing. …

How to sign with PDAs
I'm not sure what exactly you mean by "signing PDA".
A PDA is a program-derived address that by definition is off the cure, so it doesn't have a private key and therefor cannot sign anything. … However, the cool thing about PDAs is that the program that the PDA is derived from can use invoke_signed which will then be handled by the Solana runtime as if the PDA had signed the transaction. …
