If an uptick in spam is impacting your account, use this article for recommended actions you can take to discourage spammers who might try to target your account.
These tickets may have the web_widget tag, but in observed cases, the tag is actually added by the spammer. In the events of the spam ticket, look to the very bottom of the page, and see if the ticket was submitted via Web Service. This indicates the ticket was created via API (see the article: How are ticket channels defined across Zendesk?).
The primary goal of spammers is to use your triggers to pass spam content to other users via placeholders. To that end, we recommend removing placeholders from the default Notify requester of received request trigger. If you have customized triggers, remove any of the placeholders that pass the comment or title content of the ticket to the end user upon ticket creation.
Step 1: Remove placeholders that spammers target
In this example, we're updating Notify requester of received request.
- Under Meet ALL of the following conditions, add the condition Current User > is > (end-user)
- Under Actions, refer to the Email subject and Email body fields. Remove these two placeholders
Removing these placeholders renders your trigger useless to spammers, since it will no longer share their spam content with recipients. This will not immediately stop the flow of spam tickets, but will prevent spammers from reaching end-users, and you should eventually stop seeing spam come in.
Step 2: Create a new trigger for agent-created tickets
In step 1, we removed the placeholders that give your users context about tickets created on their behalf. If your agents create tickets on behalf of end-users (for example, sending out proactive emails), you'll need to create a new trigger that notifies users of the content of those tickets (but doesn't allow spammers to do the same).
In this example, we create a new trigger that we'll call Notify requester of new proactive ticket:
- Under Meet ALL of the following conditions, add the following conditions:
- Ticket > is > Created
- Privacy > is > Ticket has public comments
- Current user > is > (Agent)
2. Under Actions, select the following actions:
- Email user > (requester and CCs)
- Email Subject:
- Email Body:
This ticket was created on your behalf.

Temporarily blocking email domains using the blocklist
While the above recommendations will protect your account from further spam, it will not immediately stop ticket creation. If you want to block ticket creation regardless of channel, you can use the blocklist found under Admin >> Settings >> Customers, with the blocklist modifier suspend: or reject: prepended to the domain.
blacklist: reject:email@example.com suspend:qq.com
