I just received the same mail myself (today, 10th).
Clicked on the T&c's link - blocked by ublock "because to the following filter: ||exponea.com^"
Tried the 'Log in' link right at the bottom - had forgotten the password, so asked for a reset link in e-mail.
Got that, and responded with a new password which was apparently accepted, because I logged in with e-mail id and (new ) password, only to be confronted with a requirement for 4th 8th and 10th letter of my memorable word.
Could not exactly remember that word, so asked for the reminder to be displayed - that led to my remembering the memorable word.
But it is only 9 characters long...
Clicked on the link for a memorable word reset. Was told that e-mail had been sent. It didn't arrive. Requested the e-mail again and it finally arrived.
Another link in the e-mail to get to the memorable word reset resulted in ublock again blocking the page, objecting to the same filter as before.
Round and round we go...
Why why bloody why is it so effin difficult!!??
