Very much a work in progress! But I needed somewhere to stash these things as I make and improve them. So apologies for the total lack of aesthetics.
A section to be added to as I create things. Below is a bookmarklet which when on the tagset page on AO3 will download the freeform tags as a CSV file. Note that this is only the freeforms for freeform matching exchanges (e.g. Smut Swap) and it will not download the fandoms/ships/characters/etc in the tagset. To use this, simply drag the below link to your bookmarks, or copy it and create a bookmark manually. Then go to the relevant page, click it, and you should be good to go! (If you click it on other sites it will download, but will be an empty CSV file.)
This is designed to hide all entries and comments made by a particular user on Dreamwidth. As of now, it's very simple, so it will completely block the entry/comment. If you want to see what was blocked you'll need to turn the script off. Currently there are options to whitelist based on keyword or based on what comm something is posted in. The script will need to be edited manually to add to these three lists (pseuds, keywords, comms). If you reinstall the script it will delete everything you've added, so be warned.
You will need to have Tampermonkey or Greasemonkey installed to use this. If you have that done, click here to install.
