Adding Upvotes to a new comment in a old thread

When you post a new comment on an older Reddit thread, you need to be careful with how upvotes are added. Adding too many too fast is one of the easiest ways to trigger Reddit’s spam systems.

The safest approach is to drip-feed upvotes over time.

Note:

If you are adding a comment to a new Reddit thread, the strategy is different. Make sure to follow the guide here: [Adding upvotes to a comment on a new thread →]

Why drip-feeding matters

Reddit is very sensitive to new comments on old threads suddenly receiving a lot of upvotes.

When this happens, the comment often:

Gets flagged

Gets shadow-hidden

Or gets removed by a moderator

Drip-feeding makes the engagement look natural and avoids these issues.

Safe upvote strategy

Keep it slow and steady.

1–2 upvotes per day is the safest range.

Avoid sudden spikes.

When to start upvoting

Do not start immediately.

Wait at least 3–7 days after the comment is posted before upvoting begins.

The older the thread, the longer you should wait.

How Engain handles this

Engain analyzes the thread and determines how many upvotes are needed for your comment to reach the top position.

Instead of guessing, Engain:

• Looks at the current top comment

• Calculates how many upvotes are required to rank above it

• Delivers those upvotes gradually using a drip-feed schedule

This keeps the growth natural while still aiming for top-1 visibility.

Example setup

A safe setup for an old thread typically looks like this:

• Start after 3, 7, 14, or 30 days

• Deliver 1–2 upvotes per day

• Continue until the calculated target is reached

Engain handles the pacing automatically so the comment climbs naturally.

Important tip

The older the Reddit thread, the slower and later your upvotes should start.

There are no official Reddit rules for this. These guidelines are based on extensive testing and are designed to keep comments visible long-term.

Summary:

For old Reddit threads, always drip-feed upvotes. Engain calculates how many upvotes your comment needs to reach the top and delivers them gradually to avoid flags or removals.
