It seems a lot more catty lately, like Facebook. Sad. I really enjoyed when things were more civil.

That's definitely a maybe....
I think people keep developing skills to come up with a response as opposed to just using the like button.

I get that. I posted a fact, without an opinion on somebody's thread. They called me a moron then blocked me. Lol.
If facts bother people we have serious problems.

I also joined in April and haven't noticed much difference. I think it's always been that way, The site seems to be more focused on growth than removing the bad apples.

I never lock anyone. Liberty and freedom of speech gives everyone the right to be as idiotic and insane as they wish to be. The rudest comments can be quite entertaining.
Having said that:

I'm a new member. The people I've had some issues with have been in their 70s and 80s. A 71 year old woman sent me a snotty message and then blocked me. I had addressed her as "ma'am" and she told me I was a bitch.

i have been here since august. i have not blocked anyone - which leaves me curious as to who has blocked me.

I don't know, I think that civility remains in certain arenas but overall society has become so much more relaxed in the manner in which they speak. Obviously, thst is mirrored here. I always try to model the conduct I expect in others and try to ignore the rest. If someone is out and out racist or sexist, then I feel duty bound to comment. I am unlikely to be crass about that. I found when I lived in USA, swearing was really quite matter of fact. I think it is perfectly acceptable to remind people to speak to you respectfully.

I try to stay in touch with the people who play nicely hear and ignore those who do not.
The yin yang of the net.
