Transparency notice: just deleted several of my posts on here and FediTips.
Someone sent abuse to me on FediTips, so I blocked them on my own server. They replied to me on here so I blocked them here too.
At this point I'd blocked them on all my accounts, I had no way of seeing what they were posting any more.
Later found out via someone else that they'd replied they were LGBTQIA+ and black and claimed this was why I had blocked them. I couldn't see this reply and I didn't know this, there was nothing on their profile or in previous posts about their background.
To avoid danger of a toxic thread developing, I deleted my posts.
