Does Reddit impose a maximum limit on how many accounts a single user can block, and if so, what is that limit?

Short answer

Yes, Reddit does impose a maximum limit on how many accounts a single user can block. According to Reddit's official help page, the current limit is 1000 users, and if you reach that limit you need to unblock some users to get back below it [27]. Many Reddit users also report hitting a 1000-account block limit [1][4][5][9][10][12][16][22][24].

Other numbers mentioned in user posts

Some Reddit threads instead reference a limit of 2000 accounts. One user asked why the block limit is "only 2000," and another said they reached the 2000 level [6][7]. So there is some disagreement in the provided evidence.

There is also mention of a different, daily limit. A Reddit developer thread reports an undocumented change that limits blocking to 50 people or bots per day [8]. The evidence does not say how this daily cap relates to the 1000 or 2000 total limits, or whether the daily cap is still active [8].

What happens when you hit the limit

The provided evidence does not fully resolve which exact total applies today, but it clearly shows a limit exists. Users who reach the total say you cannot block any more accounts unless you remove older blocks first [11]. One thread also asks about the maximum size of a block list, confirming that this limit is a real issue users run into [20].
