I seem to be alone in having a certain sympathy for the OP. I use twitter daily and have done since 2012. I have used it for work (via a work account, in the name of the business) and personally. They are in no way linked. I don't tweet or extremely rarely. I have < 1,000 followers. I follow approximately 3,000 people. I use it because it's interesting and it exposes me to ideas and individuals I would not otherwise meet or hear. I find it equal parts genius and am constantly amazed by the ingenuity and wit of people and hugely frustrating due to the professional outrage, bad faith and trolling.
Despite having never tweeted once on the subject of abortion, I found myself hilariously enough on the 'repeal shield' with many ordinary and extremely high profile people blocking me. People seek out echo chambers and attribute points of view to those on the opposite spectrum of each subject which are entire nonsense and defamatory or 'reaching' in the extreme.
It's not called the 'Hellsite' for nothing. It's entirely normal for people to be called child abuse apologists, nazis, facists and other awful accusations quite over and above the normal 'moron' or 'labour scum' or whatever you're having yourself. Twitter is ineffective on dealing with the huge volume of complaints they receive and are not consistent in the administration of suspensions etc.
All of the above contribute to why I use the site to listen, inform and entertain myself without engaging directly. So if for example, the OP was told they support rape culture, for example, I could absolutely see why they would be upset. If they were incorrectly accused of a specific crime, for example pedophilia, I would have huge sympathy. These online accusations have in real life led to vigilante activity where the wrong person was targeted. Of course I don't know what he/she was accused of but the point remains - people feel like online social media is different but it has real life consequences for people and the audience reach is immense. A resolution is rarely achievable from a fairness point of view. Add into this the very twitter phenomenon of 'Twitter do your thing' where a tweet is screenshotted or shared and people are encouraged to pile on and target the poster via their employer or landlord or whoever to finish them and real, long lasting harm is done without any of the checks and balances which would occur in the real world of allegations.
Of course all of this supposes that the accusation for the OP was a serious one but the principle remains. Twitter, and social media in general is absolutely lawless to all intents and purposes and many, including Caroline Flack have found to their detriment.
