I'm using AutotweetNG Pro on my site since a lot of time and I've seen that database usage of autotweet_posts and autotweet_requests tables are growing out of control.
Selecting the purge button in the request window does not seem to delete database records.
Can I manually delete these records from the database? Is it safe to do so?
If you prefer to delete them in the database, the query is simple and you can delete all records according to your requirements. Purge operations are defined in the models/requests.php and models/posts.php.
