Now that the "Everyone leave Tumblr because this place is a shit-hole" thing is going around again, it's a really great time to remind everyone not to push people to join a new site- ESPECIALLY if those people have anxiety
As someone with anxiety, there is nothing that will make me LESS likely to join a website than feeling pushed into it
By all means, I'm not saying you shouldn't suggest new sites, certainly do! But also be understanding when someone says "No" or "Maybe later but not right now", especially if they're neurodivergent or mentally ill as technology is not everyone's freind and some people have a really hard time with new websites, new communities, big changes, or all of the above
For alot of people, joining a new website- especially one where someone would have to essentially "move" (IE: a new art site for artists, a new fic site for fic writers, a new social media site for a fandom community, etc) is a REALLY anxiety-inducing process that they may need time to decide on and get used to, and will likely need to come to the decision on their own- or atleast FEEL like it's their decision
I 100% encourage you to offer to help if someone is interested in joining a new site or if you ask them to join one! But saying things like "You HAVE to join because-", "You NEED to join because-", "If you DON'T join-", etc, is really not a great way to handle something like this
TL;DR: Don't push people to do something they don't want to do, or are hesitant about, no matter how much YOU like something, it doesn't mean THEY will, just because YOU think something is easy, it doesn't mean someone else will, and even if you're 1000000% that they'll like it, you still need to let them make their own decision and don't be a prick about it if they say no or are hesitant
