Thats doubtful. You might be able to crawl those sites and see if you can find a matching email address inside the blog. Services don't generally allow anonymous lookups of their users info, for obvious reasons.
Get name portion of email address (everything before @), say "foobar"
Create URL "http://foobar.wordpress.com" and execute it with you preferred server technology (say HttpClient in Java)
Check response code - for the existing site it will be 200, for non-existing it will be 302 (redirect) and you can also check that you are not redirected to en.wordpress.com
You can do similar things with other type of sites that support naming conventions of user.site.com or www.site.com/user.
Of course there's no guarantee that based on the name that blog will belong to the same person, and there's plenty of blogs that have custom URLs all together
While Blogger makes it possible to go from a profile page to an email address (example 1, example 2), there's no public index of those pages.
Wordpress.com doesn't have those type of standardized profile pages, so your chances of getting something there are zero.
If you have Yahoo IDs, you may be able to look up users' Yahoo profiles, which can either reference websites the user's associated with (example 1, example 2), or contain a Yahoo blog (example).

这是值得怀疑的。 您也许可以抓取这些网站，看看是否可以在博客中找到匹配的电子邮件地址。 出于显而易见的原因，服务通常不允许匿名查找其用户信息。

不，也许吧。
虽然 Blogger 可以从个人资料页面转到电子邮件地址（示例 1示例 2），这些页面没有公共索引。
Wordpress.com 没有这些类型的标准化个人资料页面，因此您在那里获得某些内容的机会为零。
如果您有 Yahoo ID，则可以查找用户的Yahoo 个人资料，这可以引用与用户关联的网站（示例 1、示例 1 yahoo.com/white4blkbreeding" rel="nofollow noreferrer">示例 2)，或包含 Yahoo 博客 (示例）。
No, and maybe.
