If you want an “easier” way, you can search through your user data instead of mindlessly scrolling through activities.
To do this, first click on your preferences
- request a copy of your user archive
This will download a copy of your entire forums data in a ZIP file. Within this ZIP file you’ll find a lot of personal info in the form of a CSV files.
The file you’ll be looking for is going to be the user_archive.csv
