It feels like (and I might be wrong here) that most of what now stand as official/semi official twitter accounts have grown from smaller issue based groups within all the political parties.
They've been left to flourish because either the main party reps haven't had a good handle on social media or view them as more niche issues that they don't know enough about.
For example The Labour Autistic Network twitter account that was set up in January, it's not blue ticked nor is it transparent who runs it or what qualifies them to do so.
To my mind the process should be along the lines of, we want to run a SM account to encourage neurodiverse people into politics as part of a wider campaign, these are our clear aims and objectives, this is the person chosen to run the SM and here are their qualifications to do so.
At the moment it seems anyone can set up an account affiliated with a political party and conflate any number of political issues using the account as TLAN did with posts about TWAW.
Nobody seems to be stepping in to regulate any of this with some accountability.
