How to Use 9bot to Filter Links and Files on WhatsApp

The urgency of filtering in groups

We live in a time when practically everyone participates in WhatsApp groups, whether to chat with family, exchange ideas in work groups, or participate in online communities with common interests. According to market research, over 94% of active users are in at least one group, and nearly 40% feel saturated with irrelevant news and content.

Beyond the sheer volume, there is a growing concern about the type of files and links circulating in these spaces: nudity, pornography, and explicit violence represent up to 80% of the sensitive content in massive public WhatsApp groups. These statistics highlight the urgent need for automatic filtering features. This is where bots come in: tools increasingly used to moderate, block, and organize what reaches the group members.

We'll show you how to use bots to filter incoming links and files, from the basic concepts to practical examples and tips for configuring them according to your group's profile. If you manage communities, news portals, or businesses that interact via WhatsApp, this article is for you.

Why is filtering links and files necessary in groups?

Before diving into the steps, it is essential to understand why it is so worthwhile to dedicate time to moderating links and files. The indiscriminate sharing of this content brings several negative consequences, including:

• Circulation of fake news and disinformation.
• Exposing members to offensive or illegal content.
• Loss of focus on the group's main purpose.
• Risk of spreading malware and scams.
• Notification overload and unwanted messages.

Data shows that a significant portion of users feel annoyed by the excess of irrelevant information, which can ultimately lead them to leave the groups.

When dealing with large groups, whether for news distribution, business communities, or content creators, the situation amplifies. Administrators can no longer manually control everything posted—be it a link, image, PDF, or video. Automated filtering, as proposed by 9bot, adds value not only in audience retention but mainly in caring for the community's digital safety.

The role of 9bot in controlling links and files

Bots are programs that interact automatically with groups, answering commands, organizing messages, and, of course, identifying and filtering specific types of content. On WhatsApp, they are a lifesaver for those who manage multiple groups simultaneously.

The difference between a manually managed group and a bot-automated group is the day-to-day peace of mind: the administrator stops being the full-time "bad cop." The bot handles it with agility and precision.

How does automatic filtering work?

When using a solution like 9bot, filtering happens in three main stages:

Many administrators report surprise when checking the actual volume of blocked attempts in their reports, realizing in practice how necessary this feature is.

Configuring your 9bot: first steps

In our experience at 9bot, we noticed that the best results come from customization. Simply activating a generic block list isn't enough. Therefore, we recommend thinking first about your group's purpose (informative, educational, commercial, etc.).

List the types of allowed and prohibited links and files, and define which members will have special permissions to send content. It is vital to communicate the new rules to all participants before activating the bot, and to maintain an open channel for members to report unfair blocks.

The 9bot dashboard allows you to define keywords, prohibited domains, and exceptions, as well as configure automatic alerts. We also provide statistics so you can see which types of content are most attempted in your group, allowing you to adjust your rules over time.

Effective rules: practical examples

Knowing various profiles and needs of 9bot clients, we selected examples of simple and efficient rules that you can apply today:

• Blocking shortened links (like bit.ly, tinyurl): prevents redirection to malicious sites that are hard to trace.
• Prohibiting executable files (like .exe, .bat, .js): excellent in business groups or with less tech-savvy participants.
• Restricted words in links (terms related to pornography, gambling, violence): great for news and public discussion groups.
• Permitting only PDFs and images: valid for school, religious, or strictly educational communities.
• Links only sent by administrators: useful when the group has an institutional focus and only official content should circulate.

The secret is to adapt these ideas flexibly and review them periodically, because threats and behaviors change.

Checklist: Errors to avoid during setup

It is easy to get carried away with automation and create excessive blocks. A very restrictive group can alienate members or prevent the circulation of legitimate ideas. Striking a balance between security and freedom of participation is the greatest challenge for administrators. Check off what you are already doing:

Advanced customization tips

After the first few months, we recommend fine-tuning based on the group's real situations. Some advanced 9bot features include creating conditional rules by time (e.g., files allowed only during business hours) and temporary permissions for specific members to send different types of files.

It is also possible to set automatic alerts for spam attempts at night and automate responses that encourage behavioral correction within the group itself.
