Tell me, does this help with website promotion?

I'm registered on many forums, where I have my own threads about the store.
I notify customers about new product additions to the store directly in the thread.

I started translating this text into the seven most popular languages and began publishing it.
Example text:


The site sells various digital products, proxies, accounts, activation keys, and promotion services. Here are the main product categories we've added today:
And below I'll list the products I've added.
Le site propose divers produits numériques, des proxys, des comptes, des clés d'activation et des services de promotion. Voici les principales catégories de produits ajoutées aujourd'hui :
Vous trouverez ci-dessous la liste des produits ajoutés.
El sitio vende diversos productos digitales, proxies, cuentas, claves de activación y servicios de promoción. Estas son las principales categorías de productos que hemos añadido hoy:
A continuación, listaré los productos que he añadido.


This is how I translate one text and others in other languages.

Can you tell me if this helps my website's promotion?
Or will it actually hurt its rankings and lead to my account being blocked on forums?

I think it can help with visibility if each forum thread is genuinely useful to the people reading it. Posting the same translated text everywhere would be the part I'd be careful about.
