# Adding upvotes to a new comment on a new thread

If you want to boost a new comment with upvotes, **thread age matters** for Reddit’s filters.

### New Threads (Less Than 30 Days Old)

**Safe to Send Bulk Upvotes**
You can safely send a large number of upvotes to your comment **instantly**. Reddit’s spam filters are much more lenient with new threads, so there’s little risk of your comment being removed.

**Pro Tip:**
The newer the thread, the safer it is to send upvotes quickly.

### How to Add Upvotes
* Go to CrowdReply and place your upvote order on the comment.
* Instant upvotes are safe to use on **new threads**.

### Older Threads (More Than 30 Days Old)

**Safe Strategy**
For comments on older threads, **do not send upvotes immediately**.

Based on extensive testing:
* Let the comment age **at least 10–14 days**
* After this period, you can safely send **all upvotes in one go**
* Sending upvotes earlier has a **high risk of triggering Reddit’s sitewide filters**

**Why?**
Reddit is highly suspicious of new comments on old threads that receive engagement too quickly. Once the comment has aged past ~10 days, Reddit becomes significantly more lenient.

### Note
These are guidelines based on real-world testing. Reddit doesn’t publish official rules, so when in doubt, **waiting longer is always safer**.
