I subscribe to RSS feeds for subreddits that don’t exist on Lemmy just so that I don’t give them any clicks or ad revenue.
For answers to questions or problems that are only available on Reddit, I turn on my favorite privacy browser, I hold my breath, go to that specific post, get my answer, and gtfo asap.
Like the saying goes, never stick it in crazy. But if you have to, be protected.
Exactly my current setup :)
