account names cannot be changed.
you can only change your display name, which is available in the settings.
whether display names or usernames are shown depends on the interface/client and user settings where available.
the only way to change the username is to create a new account.
it seems to have become more frequent recently.
i’ve been experiencing the same on firefox and i’ve also heard other people report the same on firefox, which happened around the time of the firefox 129 release. i didn’t see anything noteworthy in the release notes though that’d explain this. it seems like it might be related to enhanced tracking protection and cookie isolation.
this is a lemm.ee limitation, not a Lemmy limitation, so this is the wrong community.
if you look at the instance sidebar at https://lemm.ee/ you can see that it’s 4 weeks.
What do you mean by “finish federation”?
Generally, individual activities (subscriptions, posts, comments, votes, etc) are federated within less than a minute of them being created. Your instance learns about other instances e.g. from votes seen on other instances. You’ll need to start subscribing to some communities on other instances to get started. You may want to check out Lemmy Explorer or Lemmy Community Browser to find communities and Lemmy Federate to automatically subscribe to other communities and get content sent to you.
The allowed instances list means that the instance will only connect to those instances and will refuse to send activities to any other instance.
for content that was not federated prior to defederation, yes.
this is by design. actor ids (unique identifier for accounts) should not be reused due to undefined behavior for how other instances will deal with that.
if you want to have a more technical explanation, https://socialhub.activitypub.rocks/t/reuse-of-identity-channel-addresses-revocation-reissue-of-keys/2888 does a decent job at explaining some of the issues with this.
except instance A will actively reject such content from B users when it hears about it from C.
generally it should be expected not to see any new content from B, but historic content will still exist and basically be in a frozen state.
the main problem is still that reports are not reliably getting to remote moderators: https://github.com/LemmyNet/lemmy/issues/4744
other than that it should be working.
starting with 0.19.4, at least user settings will default to their browser’s accepted languages on registration: https://github.com/LemmyNet/lemmy/pull/4550
this doesn’t solve actually tagging content, but it some progress at least.
ah i was misreading your comment, i thought you were talking about the sending side. for the receiving side i agree, but the reason for the duplicate activities is yet to be found: https://github.com/LemmyNet/lemmy/issues/4609
records can’t be duplicated in the database, the activity id is a unique key:
lemmy=# \d sent_activity
Table "public.sent_activity"
Column | Type | Collation | Nullable | Default
-----------------------------+--------------------------+-----------+----------+-------------------------------------------
id | bigint | | not null | nextval('sent_activity_id_seq'::regclass)
ap_id | text | | not null |
data | json | | not null |
sensitive | boolean | | not null |
published | timestamp with time zone | | not null | now()
send_inboxes | text[] | | not null |
send_community_followers_of | integer | | |
send_all_instances | boolean | | not null |
actor_type | actor_type_enum | | not null |
actor_apub_id | text | | |
Indexes:
"sent_activity_pkey" PRIMARY KEY, btree (id)
"sent_activity_ap_id_key" UNIQUE CONSTRAINT, btree (ap_id)
verification emails are usually sent immediately. if there are delays you should check your junk folder, and if it’s not there it probably won’t arrive anymore. depending on the instance you signed up on there may be alternative methods to reach out to the instance admins about this. note that private messages from mastodon to lemmy do not work unfortunately.
