I am not so sure about this decision, although maybe it's the right one. Previously TERB could make the argument that it was just a neutral billboard on the internet, so to speak. People or companies would advertise their services, and TERB would put those advertisements up without judging the merits.
By taking this position, now, perhaps TERB has strayed into the territory of judging what's appropriate or not. Effectively TERB's position has become 'we do not condone sexual behaviour between consenting adults in this time of lock down because the public heath authorities would not approve'. I am not convinced the public health authorities approved even when there was no Corona on the loose though, so perhaps little has changed in terms of their position.
I think it's a slippery slope, although the position might very well have merit to it.
Speaking of a slippery slope, in self iso lately I have been catching up on Netflix movies. Just re-watched Cliff Hanger with Sly Stallone - first time since it came it. What a great movie. I don't think any other movie since 93 has started off the way this one did, just totally unexpected what happens in the first ten minutes. If you haven't seen it before, I do recommend.
