I subscribe to several block lists on Twitter, as part of my efforts to avoid drama. One of the lists I subscribed to turned out to be much too aggressive, and I suspect that I’m blocking a bunch of people that I probably don’t really want to be blocking.
There are about 9000 people on this particular list, so unblocking them manually is highly impractical, and unsubscribing from the list does not unblock them. So I downloaded this list as a CSV file, and wrote a python script to go through it, automagically unblocking them for me.
A couple of features:
- It unblocks 100 IDs, then pauses for 8 seconds, so as not to run afoul of the Twitter API rate limit.
- The CSV that you get when you export your block list from Twitter, isn’t really a CSV, because there is only one column in the file, and no delimiters of any kind. So rather than import the CSV module and read the file as a CSV, I just have it reading the files like any text file. It works fine.
- I wanted to get an email when it finishes the list, or when it encounters errors, so I pasted in an email function that I use quite a bit in other scripts.
- This does require having a Twitter API key. There are many sites out there with instructions on how to obtain one, so I’m not going to cover that here. I already have several, as I have several Python scripts running a variety of Twitter tasks for me.
- Added in some error handling.
- Added command line arguments so that you specify the list file in the command line, and can optionally specify a line number to start from if the script bombs out partway through. This was happening frequently while I sorted out how to deal with trying to unblock deleted twitter accounts and such. Instead of erroring out, it now simply moves on to the next line. Not so much an issue now, but the capability is still there.
