Are you using any addon to craft Writs and in that case which add on as there are some that either do only MasterWrits and other that do all Writs except for MasterWrits (they can, but addon on author/those that keep maintaining said addon recommend strongly to use another addon for that).
Have you checked in the case you addon that you have the last version from using Minion to update and check directly on ESOUI.com where add on have their page and can be downloaded if anybody else are reporting issues?
I myself use Dolgubon's Lazy Writ Crafter (updated 4/22/2024 according to page) and some other related to crafting Writs and MasterWrits. You need to check if those add on are from at least 2023 as game API might have changed and how fast any commands might be sent to server before it trigger a warning and then a ban, if you just ignore that warning.
Also turn off any addon that hides/suppress error messages from addon as that could also be a reason that you get social ban as you don't see when an addon might get error and then just continue to use that addon which will end with social ban.
It is also possible that the server you are connected to is overloaded at that moment and that is why get a social ban.
If you use any addon for chat it is very important that you make use of the last version that is close in time (2023-2024) and not stubbornly keep using an old addon that still might work on surface, but can causes issues like this. From what I know there was some changes for Chat addons that they need to have a longer delay between each command and that includes addon which handle Guild (rooster and sales( are other example with large number of data might be requested from server that can trigger social bans.
In short rule out that you don't use too old addon and which addon that is the culprit.
If you don't use any addon at all then it is your own fault that I wrote this long message as I can not access any info about your forum account which normally would at least explain if you where on console or PC, or show any older posts to have any idea if you already have expressed that you had done this research and systematic worked down what could trigger your bans.
