When old.reddit.com dies, how will Lemmy grab more users?

I don't see Old Reddit lasting long. They've cut beloved features before, and they're still calling New Reddit a "beta feature". After they've pumped enough resources into developing it, I'm sure they'll move past the "test" phase and just cut Old Reddit out entirely. That's probably going to be Lemmy's next big user surge.

Does Reddit suppress mentioning Lemmy? I remember for a while this past June 2023 there were a lot of auto-deletions for mentioning or linking to Lemmy. I was never clear on who was deleting things and where. I guess linking to the r/Lemmy subreddit (or a fediverse sub) could work as long as the subreddit doesn't get banned.
