From the Daily Mail article:
The student union suspended the organisation pending an investigation, while the university said the tweets were 'inappropriate'.
And
A spokesman for Goldsmiths, University of London said: 'Goldsmiths has a diverse and inclusive community with many people caring deeply about trans rights.
'In this exchange, the language used was clearly inappropriate and we support the decision of the Students' Union to suspend the student society with immediate effect.
We will work with the Students' Union to ensure continued support and representation for LGBTQ+ students.'
And
Goldsmiths Student Union said: 'We condemn the abhorrent content of the tweets and they are in complete opposition to the views and values of the Students’ Union.
'The society have broken multiple union policies and procedures, including failing to adhere to our code of conduct, and we have issued multiple requests for the group to delete the tweets.
'As such, the society have been suspended and disaffiliated from the Students’ Union, pending investigation.'
This is what 'account locked due to safeguarding' means.
It looks like Both the individual involved AND the entire society are now under investigation.
I believe I'm right in saying @LGBTGold has now been deleted from twitter too (I'm getting user not found).
After this it's hard to see Goldsmiths not watching and monitoring LGBT activism at the university like bloody hawks.
What a damn shame.
It really has damaged the university's reputation and a lot of Goldsmiths grads who aren't part of this political cult are going to be mighty piss at how it reflects on them - and they are important to the university and have influence elsewhere in power.
