Osortoo provides several filters to help you manage the participant list and ensure your giveaway rules are respected.
These filters work for Facebook, Instagram, YouTube, and mixed-platform giveaways, depending on the data allowed by each platform.

Below are all the filters available and how each one works.

1. Remove duplicate users

This filter removes repeated entries from the same user.
If a participant comments multiple times, Osortoo can count them as one valid entry.

Useful when your giveaway rules state:

• “1 comment = 1 entry”
• “One participation per person”

2. Minimum number of mentions

This filter checks how many people were tagged inside each comment.

Examples:

• Tag 1 friend
• Tag 2 friends
• Tag 3 friends

Only comments that contain the required number of mentions remain in the eligible list.
Works on Instagram and Facebook, depending on the comment structure.

3. Keyword include filter

You can require comments to contain specific keywords or phrases.

Examples:

• “Write your favorite product”
• “Comment your city”

Only comments that include the required keywords stay in the list.

4. Keyword exclude filter

You can remove comments containing unwanted words.

Useful to:

• remove spam
• exclude bots
• filter inappropriate words
• enforce rules about what the comment must NOT contain

5. Blacklist specific users

You can manually exclude users who:

• did not follow the rules
• posted inappropriate comments
• were selected as winners in the past
• must not participate in the draw

Blacklist entries are removed from the participant pool.

6. Filter by comment date or time (when available)

Some giveaways have start and end times.
This filter removes comments posted:

• before the giveaway started
• after it ended
• outside the allowed time window

This ensures only eligible comments are imported.

7. Remove comments without text

Some comments contain only:

• emojis
• empty tags
• blank content

This filter removes comments that do not contain any meaningful text.
Useful when your rule requires a real answer.

8. Unique user filter (strict mode)

This mode combines duplicate removal with stricter validation.
It removes:

• repeated comments
• repetitive patterns
• bot-like entries

Only one clean entry per user remains.

9. Platform-specific filters

Depending on the platform, Osortoo may apply additional checks:

Instagram

• tag count
• minimum mentions
• removing restricted comments (API-based)

Facebook

• text-based rules
• removing comments from hidden or banned users

YouTube

• only public comment retrieval
• exclusion of held-for-review comments

10. Multi-platform filtering

For mixed giveaways (Facebook + Instagram + YouTube + manual entries), filters apply to all imported participants.

Examples:

• remove duplicates per platform
• keyword filtering across all comments
• blacklist users from any platform
• date/time filtering where applicable

Osortoo keeps platform identities separate, so “@alex_01” from Instagram does not conflict with “Alex Jordan” from a Facebook entry.
