Since the thread I posted a reply on is one of the deleted ones (for being triplicate), I’ll add here what I said in that thread (no need to self-quote my post, since it was deleted along with the thread):
While some ideas of the kind is recurrently brought up on Meta, favouring Newbie accounts being more restricted to where they can post (and even to the frequency of posting), the current stand is no:
<…> Limiting newbie participation is very harmful for a community. Newbie jail will never return: I consider the newbie-jail period to have been extremely damaging to the forum. When barriers to participation are too high, then the best people often just won't go to the trouble of joining, and the people who are willing to jump through the hoops are often people who aren't good for the community: people with nothing better to do, scammers, get-rick-quickers, etc. Having a permanent newbie jail policy would improve things a lot in the short-term, but would end up being a fatal poison to the community. <…>
In the specific case of your thread, the accusations have not caught eco so far (or maybe even spotted) by any DT member yet, and thus there is no related trust feedback not flags/banners. That would be a grave stain to your account and threads, but requires a certain protocol that entails going beyond a mere accusation post on your thread created by a Newbie account, as is the case. So far, that front is in the clear.
As to the Newbie accusatory posts, you can report them if you wish. They may or may not be deleted though. Nevertheless, it would be good to refute their accusation which is mainly based on the photograph of the same person with apparent different names on Twitter and Wikipedia. That should be addressed with a plausible explanation, just to leave a written counter-argument to the alleged accusation (I did not find it on your thread, but I may have missed it).
You could also open a post in
Reputation if at this point you consider it necessary, in order to get other people’s feedback.
