I thought there was already a twitter thread but it's not, but here was my personal overview

Although I have to add, Twitter can be a LOT of work. You feel obligated to constantly have new content to keep people interested, people who aren't paying for it. It always paid off for me in the bookings I'd get as I said in that other linked reply, but I know some people don't get a lot of business from it at all. Know your limit going into it of how much time you want to invest in taking/editing photos, posting them, and engaging with other SWs tweets, or I promise it will become a huge time drain.
Also, given the likelihood you'll be posting more candid snaps than you would on directories, do so with caution. It can be easy to slip into giving away things in the background, your local park that you visit daily for a run/walk, your favourite coffee shop etc. Don't post pictures of inside a hotel room that you're still currently in, and be discreet if it's one you use regularly. You never know what creeps are lurking on your whereabouts and trying to look out for you IRL (that includes hotel staff).
There's also been a big hooha recently about them getting stricter about SWs on the platform, so the advice is to make sure your header image and profile image are clothed, and any nudity/nips through a sheer bra/ bum crack are marked as 'sensitive' so as to not trigger the shadow bans/account deletion, though it's safest to make sure you're at least wearing lingerie/suggestive outfits as opposed to full nudity. You can even get shadow banned for silly things like using the F word, the word 'sex', hashtagging, retweeting too much, not tweeting enough. It's incredibly frustrating when it happens - it basically means your posts get shared with far less of your followers, so you have barely any engagement and posting feels like you're just screaming into the void. It usually gets lifted if you just stay inactive for 3 days and/or delete the offensive content, but that's a whole different dicussion.
