Posting an address is not the same as using it. Anyone can post it, only the real owner can sign a message from it. You can't link accounts based on an address they post, anyone can post an address I've posted, but that doesn't mean they're my alts.
A huge number of users have been banned based on this principle. And not once have I come across any complaints about it. In any case, I have not seen any serious complaints. The thing is that no one will check whether the address was published on purpose or the address really belongs to the alts. This is practically unrealistic. But if after the ban the user will write a rebuttal in Meta, then the moderators will consider this case. But then again, it is almost impossible to prove.
Again, if someone publishes your address, it will be after you have published it. In any case, the publication of your address from someone else will be later than yours.
And anyway, what's the point of publishing someone else's address? The user will be playing against himself. After all, his post will be published later anyway, which means he will be banned in the first place.
Here's theymos' address: 1NXYoJ5xU91Jp83XfVMHwwTUyZFK64BoAD 
That doesn't make me theymos!
That doesn't make me theymos!No one is talking about that kind of thing. Matching elements from the profile as proof of a connection between accounts is not considered, IMHO. Matched items should be placed exactly in forum posts.
P.S. Well, if someone dares to publish your address without your knowledge, the global moderators will surely ban you
