No idea about this from the network perspective, but I want to point out
they started intermittently blocking Tor about the same time they had
their third-party app tantrum (i.e. early 2023). You get HTTP 429 and a
blank screen. Presumably they're not explicitly blocking Tor, but also
not exempting it from standard rate limits, making it useless if other
people or systems are also accessing it through Tor. Sometimes you can
load a few pages.
It feels like Reddit's jumped the shark since that time period, not too
dissimilar from Twitter. Some people reported that you can now get your
IP address banned for upvoting memes about the Nintendo character Luigi.
It might have been worth trying to get unblocked if they were still a
serious site, but...
FWIW they're allegedly blocking all search engines other than Google,
who paid them a lot of money for the exclusive right to show them in
results and use them for AI training. That's one reason they suddenly
switched to trying to keep everyone out. For a while they were
specifically trying to block Microsoft because of OpenAI.

Anyone reading from Reddit? We've been getting a "Blocked by Network

a ticket open with support has gotten no useful replies.
Sorry if this isn't the response you were hoping for, but maybe a
piling on will help highlight that yours isn't an isolated problem.
I've seen this from some random address space too. They seem to
dislike some prefixes if they are typically associated with servers for
instance, but are perfectly OK with Tor. There seemed to be a change
to their blocking about a year or two ago. I've never been much of a
reddit user and it seems so arbitrary that I've not bothered to open a
ticket with them. Instead I just stop trying to click on reddit
links that show up in search engine results. *shrug*
