# Account Checks

Guardian can screen new members before they even reach the verification step, blocking common bot patterns at the door.

Pretty sure you've seen this before...

Bots joining groups with contract addresses in their display names, in effect mass-spamming scrapers scanning for new tokens. It's irritating, and it can affect traders scanning for legitimate tokens.

Enabling **0x Address Check** will solve the problem.

Enabling this check blocks any account using an Ethereum-style 0x address as their display name from passing verification.

Similarly, **Link Check** blocks accounts whose display names contain URLs or website-like text.

Both checks can be enabled in your Guardian settings.
