Feature Request: More selective deletion or whitelisting options

[NadyaNayme]

• Being able to whitelist or delete tweets that contain a specific hashtag (or word?)
• Being able to whitelist or delete all Reddit posts in a specific subreddit.

I regularly delete both my Reddit posts and my tweets - however I do so in a more staggered fashion than many people might. Different things have different time lengths of relevance. There are some tweets I delete weekly, while others may last a month or more. There are some subreddits where I would prefer to not delete my post history.

Whitelisting hundreds of posts one by one in a given subreddit isn't practical for most people, even as a one-time thing. I've already done it once, using a different Reddit-post-removal tool, but I'm not sure I'd have the time to do it again. I haven't deleted my Reddit posts in a while - and this is largely because I haven't had the time to go whitelist every post I've made in a specific subreddit.

I'm not sure if this is possible - as I imagine the program currently works based on its queries to the API and doesn't do any additional filtering on the user's machine. I'm not sure if Reddit allows searching by subreddit...
