Creating an account allows smart people to identify their email address

I run a blog site.

When posting a blog, I think that the user must first create an account, but after creating an account with an email address and the administrator grants posting authority, you can post a blog.

What I'm concerned about is the member part such as the profile.

Recently, the blog list is displayed under the profile, which is wonderful.

However, the email address used when creating the account is the account ID (community ID), and a wise person can guess and misuse it.

I made an inquiry by phone the other day, but he said that there was no solution other than keeping his profile private.

We strongly request the function that the security is weak in the present society and the account ID (community ID) can be changed as in the past.

I think the post here is out of place, but I posted it because I want to tell you.
