I saw a poll like this last week, but I thought it would be cool to do it again with another major migration underway. Boost so we can get a better sampling.

Report back from Twitter filter fuzzing.

What Twitter is blocking

• Twitter is filtering links to known Mastodon instances, but still allows direct links to joinmastodon.org. The filtering seems to happen whenever Twitter's WSYWIG editor recognizes a valid domain name and that domain happens to be a known Mastodon instance.
• Twitter also allows linking to shortened URLs of mastodon profiles, but only once. Posting the shortened URL a second time doesn't work, implying there's some backend queue service that's checking the Location header of links and flagging the ones redirecting to Mastodon instances.

How to evade the filters

• Email address spam evasion techniques work. Replacing '.' with ' . ' or [.] or [dot] all work.
• URI encoding the hostname. Replace at least one of the characters in the hostname with the URI encoded version (ex: https://infosec.exchange -> https://infosec%2Eexchange). Browsers are smart enough to URI decode anything you copy/paste into the address bar.
• data: URIs. Twitter does not seem to check base64 encoded data: URIs. It is possible to create a data:text/html;base64,... base64 encoded HTML URI which can be copied into the address bar and will render as HTML. While Twitter will not render data: URIs (for obvious reasons), you can still copy/paste them (at your own risk, of course).
• Base64. This seems silly, but we could communicate freely on Twitter by simply Base64 encoding our tweets.

Twitter's anti-Mastodon filtering is clown shoes amateur hour.🤡​

PSA for for pretty much everyone, even those who aren’t new - there is another mass migration underway. Meaning lots of accounts are being created on instances all across the fediverse, and the people behind those accounts are exploring, introducing themselves, and so on. Some instances handle this load better than others.

PLEASE NOTE: while you can migrate an account to a new instance and your followers will move with you, however doing so during times like this may cause that to not work correctly.

Please be patient with instances that are have trouble keeping up. They will get it under control. We are all doing the best we can. Most all instances are funded by donations from members. If you are able, look at your instance’s /about page and consider donating.

Made in solidarity with the #ForestDefenders in #Atlanta.

Fuck the cops and their plan to deforest to make way for “urban warfare” training. Replacing city green space with murder training grounds is fascist as fuck.
