The owner of a trademark has a legal tool at their disposal that can be compared to a nuclear bomb . It allows to quickly cut off an unfair competitor from customers… without court intervention.
By sending a complaint about such a right infringement you will remove:
 competitor’s offer from Allegro, Amazon, OLX, or Etsy;
 company account on social networking sites such as Facebook, Instagram, YouTube or TikTok;
 Google Ads using the reserved word.
Naturally, such a company can also be sued, but you have to reckon with the fact that the process may take several years. If you cut them off from customers earlier, they may be more willing to quickly settle. So, by investing in formal brand registration, you ultimately save money .
