I've said it before but I'll repeat it: the Twitter process cannot possibly be automated.
If it was, Twitter would collapse. Because if this algorithm existed and could be games in the way TRAs are alleged to be gaming it, other political groups would be doing the same for their pet causes. Brexiteers would be getting Remainers accounts taken down and vv. Trumpites would get Democrats accounts taken down and vv. Momentum dudes would be taking down the accounts of Centrists.
If such an algorithm existed everyone could in principle abuse it - and a lot of groups have the motivation to do so. Yet it is only GC feminists we see on the receiving end. This is being done using human intervention - it has to be.
