I have started encountering inappropriate ads showing up all over MTS, both large square ones and small text ones.

They're not sexually explicit, but they are very much suggestive. They're displayed in my language (Croatian) and read "hi hottie, can't wait to meet you, dying to get to know you, I need company," etc. I checked my browsing history in case I looked up anything that could be misinterpreted as porn, checked twice, but I didn't find anything.

I did report the ad to Google, but it keeps appearing, so I'm posting here in case it needs the site owner's attention as well.

Edit: the ads went away eventually.
