For anyone interested in doing the same, use shreddit.com. This also deletes all your comments, posts and votes.

Have done the exact same, except I deleted all comments and posts (with shreddit.com if you want to do the same) and left only one post: a statement about the whole reddit API fiasco (and how it is unacceptable) and my lemmy username and instance.

I deleted an 8 and 12 year old Reddit account with a combined 100,000k karma. Deleted all the content along with it.

I would go a step further and delete all your posts / comments that are informational / useful.
