🌍 Blocked Prefixes - Block by country

This tab lets you block numbers coming from specific countries. Especially useful when most spam comes from a fixed source.

Why block whole prefixes?

The statistic is clear: 80% of spam in WhatsApp groups comes from foreign prefixes (mainly Asia and Africa).

With one click you block thousands of potential spammers without affecting any real customer.

Blocks everything that's not your country code. Useful for local-only groups.

You can add specific prefixes:

Click "Add prefix"
Enter the prefix (e.g., +234 or just 234)
Choose action:
- Block immediately — removed at join time
- Log only — monitoring mode
Add a note (optional)

The table shows for each prefix:

Column	What it is
🏳️ Flag + country	Quick identification
📞 Prefix	The number itself
🚫 Blocked	How many people were blocked with this prefix
📅 Date added	When you decided to block
⚙️ Actions	Edit / remove

Add them to the whitelist. The whitelist overrides prefix blocking.

Click the prefix ← Advanced settings ← add "Block until date".

The default is global blocking. To block only in some groups:

💡 Tip: If you manage multiple TaskFlow accounts — export from one and import to the others. Saves time.

⚠️ Don't block prefixes "just because." Make sure you understand who your audience is.

⚠️ +1 (US/Canada) also gets a lot of spam, but also expats. Think twice.

⚠️ Blocking is not retroactive in groups that already contain the people — it prevents new joins and acts on new messages.
