What is do guys purposely not like your pictures?

As an AI language model, I do not have the capability to read the minds of guys or their intentions behind their actions. However, there could be various reasons why a guy may not like your pictures on social media, such as not finding the picture interesting, not wanting to engage on social media, not wanting to seem too interested, or simply forgetting to like the picture. It's important to not read too much into someone's social media activity as it does not always reflect their true thoughts or feelings towards you.
