Ludwig's WRAP-UP
In summary, while the phrase "thoroughly because" attempts to connect the idea of being thorough with a reason, it is generally considered grammatically incorrect.

Although some examples appear in news, science, and wiki sources, it is advisable to use grammatically correct alternatives such as "thoroughly, because...", "thoroughly, as...", or rephrase the sentence to clearly express the cause-and-effect relationship. For clarity and correctness, especially in formal or professional writing, avoiding this phrase is recommended.
