I can no longer blok the reactions on a tweet

I loved this add-on, I've used it to the tune of 300+k blocks.

However, It no longer works. It just errors out before it even starts running a block list.

Unfortunate, but that's how it goes.

Works well enough for blocking all followers of small accounts. Large accounts, not so much, as the cap is 500 blocks per run. After 500 blocks, the add-on logs you out of your account.

Twitter also detetcs 'suspicious behaviour' when you try to use the add-on multiple times and automatically issues a temporary suspension of your account.

Therefore, Red Block is unusable for real mass blocking, as it will take far too much time to block, wait a while, block, wait a while... etc.

Just rarely works well. Can't even properly block 500 accounts and still will trigger a force logout. It'll get maybe 200-300, but after continuous logouts and an eventual temporary suspension, it's just no use for accounts of 5,000 or more
