Let's say there's a scenario where you want to have a footnote, but you don't want a counter associated with it. In order to stay consistent with the document style, the solution should use `\footnote` within its implementation.

```latex
\newcommand\blfootnote[1]{
\begingroup
\renewcommand\thefootnote{}\footnote{#1}
\addtocounter{footnote}{-1}
\endgroup
}
```
