Twitter is rejecting posts containing JSFiddle URLs
It’s due to crypto scammers using it. From the founder’s post:<p><i>At some point in the past crypto scammers used JSFiddle to host pages with a wallet code and posted links to that on Twitter.<p>Due to the nature of JSFiddle, anyone can post anything, so wallet codes are ok – we did implemented a content filter to shadow-ban these.<p>I asked Twitter if they they could help out and ban twitter accounts that were posting scam tweets that included links to the rouge fiddles.<p>Twitter just went the easy route and blocked all jsfiddle.net links instead of blocking spammer accounts on their platform.<p>Tried to contact Twitter many many times, with no reply whatsoever. They most likely have no-explanation-needed-policy, which is why they never replied.<p>There's nothing that can be done here unless somebody has contact to a higher op at Twitter who has the decision power to help out here.</i>
