@mmasnick hacking twitter's ban to link mastodon in profile:
1) type something similar
(m4stodon, màstodon, mast0don...)
2) use a url shortener to link to your mastodon's profile
that works.
(as for now)
eventually will force twitter to devote programmers to update this and follow shortened links as well... might break all shortened links in preexisting twits... a mess...
HTTP 301 don't work.
HTML META in HEAD works, and JS redirect.
Write a generic redirect HTML file
<script>
window.location = window.location.search.substring(1);
</script>
And call like
http://<_html_location>?<any_mastodon_url>
works (without preview of course).
If can be useful to anyone...
@clodo @mmasnick one hour ago still worked (at least for me). now it doesn't
:-(
