Hi @Pilar_Pereira, sorry about the delay in following up on this.
After further investigation, I’m sorry to say that it looks like your mems have been deleted some time around your first post in April 2020. Let me explain a bit more why this happened:
Here at Memrise we have a system that detects suspicious profiles, based on inappropriate/spammy content posted in mems, usernames, and - in the past - profile bios.
We first found out that this was happening in 2017-2018, when we had to implement this system to keep the Memrise website safe for all our customers. Unfortunately this is still happening every now and then.
Why does this happen?
As I said, in 2017-2018, we discovered that a number of Memrise users had used the same email address/username and password for their Memrise account and other web services. One or more of these third-party services had suffered a security breach at some point in the past, which allowed someone to access the affected Memrise accounts fraudulently using the same details.
The affected accounts may have been used to post inappropriate content (such as spam) on our platform, for instance by editing the username or creating inappropriate mems. It sounds like this is what happened in your case.
Once this happens and we detect a suspicious profile, we take appropriate actions to make the account safe again - usually this includes resetting the username if necessary, lock down the profile and force a password reset, and unfortunately removing all mems from that user.
We looked for your email address on a public list of breached services (https://haveibeenpwned.com/) and we can indeed see that your email address and password were exposed in several data breaches, which backs my hypothesis that this is what happened.
(Please note that there has been no security breach on the Memrise account itself.)
I’m really sorry to say that your mems can’t be retrieved as they’ve been deleted forever. I’ve already raised this issue to our team, asking them to implement a better way to do this - however unfortunately I have no timeframe for this.
Please rest assured that this won’t happen again.

@Olaf.Rabbachin - Unfortunately I can’t comment further on mems in general at this time.
Best,
A.
