I don't like 'judgey', prefer 'judgemental' and have never heard someone abbreviate it like that in real life - though they probably do since Mumsnet.
Regarding other things people have cited: being 'thrown under a 'bus', is a phrase widely used and there are people who say, "No", quite plainly so it is a sentence.
Some of the acronyms are irritating. Why is everyone 'Dear' when in real life you wouldn't say, "Dear daughter, dear mum". GP could be grandparents or your doctor.
The use of swear words in every paragraph of a post, sometimes more than once per para. I would think once is sufficient.
'Rent out' rather than 'let'; that has found its way into mainstream British conversation but it isn't correct. In any case, the unwritten rule is that you write more formally than you speak.
(I have noticed when posting on here something happens occasionally where a word I thought I had posted comes out as something else, or with a 'greengrocer's apostrophe' when none was typed. I suppose we can't help that, it's down to the software.)
