This originated here:
https://bitcointalk.org/index.php?topic=5103283.msg49470283#msg49470283And I completely support the idea raised by that thread, i.e. make it easier to report certain types of posts. But until/unless that feature gets implemented perhaps you'll find my approach useful.
Caveats1. This is a browser extension. Never install browser extensions obtained from random strangers on the internet unless you know exactly what you're doing. I'm not responsible if this extension steals all your money and runs away with your spouse.
2. This is mostly-untested code. It's alpha quality at best. I gutted it out of a larger extension that I'm using for other purposes. Treat it as an example or an idea. Feel free to steal any bits and pieces that you like or do whatever you want with it.
3. It works in Firefox/Tor browser and may work in Chrome but again - untested. Probably won't work in mobile browsers.
4. You must have some knowledge of how WebExtensions and Promises work in order to make sense of the code. I'll try to explain below but a proper tutorial is out of the scope of this thread.
How this worksThis is a browser extension built using WebExtensions API and consists of two main parts:
- bct-content.js: content script, a copy of which runs on every Bitcointalk page once the extension is installed. Depending on which page it is, the content script will perform different actions:
- Inside threads, on Patrol page, and in user's post/thread history it creates one-click buttons to report posts to moderators. Clicking one of the buttons sends a message to the other part of the extension, which handles queuing etc.
- On the "Report to moderator" page it expands the comment field for better visibility. If the page was opened automatically by one of the above buttons, it inserts the pre-selected comment, waits a specified amount of time to comply with throttling, and clicks "Submit".
- In the board view it closes the tab if it came from the automated post report, otherwise it does nothing.
- bct-background.js: background script, which listens to messages from content scripts and for each message opens the "Report to moderator" in a new tab, which is then handled by the content script as described above. This is done without taking focus away from what you're doing so you can keep browsing and reporting other posts.
The code that runs between when you click your button and when the extension clicks the "Submit" button is wrapped in a
Promise so it should succeed or fail as a whole. Please note though that the actual submission of the report is not verified, i.e. if there is a failure
after "Submit" was clicked - Bitcointalk down, CF fire hydrant, etc - you'll have to double-check your report history to see if the report was submitted successfully.
If the code succeeds it will add a yellow border on the left side of the post being reported, if it fails - a red one. Styling is configurable in bct-content.css. o_e_l_e_o created a
custom stylesheet for a "blend in" look-and-feel.
In case of a failure check console log and please let me know if there is a bug that's causing it.
How to installSave the files posted below into one folder. In Firefox/Tor go to "about:debugging", click Load Temporary Add-on, and choose any file in the folder. If you're brave enough to use Chrome -
you're gonna have to figure it out on your own HCP has
figured out a way.
The actual clicking of the "Submit" button is commented out - see line 18 in bct-content.js. I would like to avoid spamming our dear moderators with a bunch of malformed reports if anything goes wrong. If you decide to use the extension you can test it first by manually clicking "Submit" and then uncomment the line once you're comfortable.
Line 19 sets the wait time before clicking "Submit". High activity accounts have a 4-seconds-betwen-posts allowance, so the default 5000ms delay works well with that. With a lower activity account you may run into throttling - adjust the delay as needed.
You can change button titles, report comments, add new buttons, etc around line 120 in bct-content.js.
Questions?I'm sure I missed something or messed something up. Feel free to comment in the thread.
