past tense or present tense can be interchangeable, it depends on how you word it. “I am irresistible” (present ongoing), or “everyone who saw this picture messaged me” (past).
Imagine being a normal person with no occult knowledge – you’re scrolling through someone’s photos and suddenly there’s a random sigil. It might not turn people away necessarily, but it might make them think “wtf?” before they can focus on it long enough for the message to sink in.
That’s why I would recommend overlaying it in your photos, or at most, adding it visibly to the corner of a photo or something. If you begin talking with someone, maybe you could tell them that you are an abstract artist, and just send them a copy of the sigil to see what they think (honestly though, again, it’s probably just going to make them think “wtf?” unless it’s a very pretty, stylised symbol in a specific art style). Alternatively, you could say that you’re trying to start a business and attempting to come up with a logo, and send them the sigil to ask for their feedback.
Plus – there is such a thing as passive charging, which is when people view your sigil and by trying to figure out what it means, they subconsciously charge it with energy.
So maybe your best bet is a combination of work. “Anyone who views this sigil is curious and aroused” or “anyone who views this sigil desires to speak with me more”. And a combination of the above: put it in the corner of your images. If you have to explain why, tell people it’s your watermark/copyright, or the logo for a business you’re starting, or something. Or, once you have established a connection with someone, ask what they think about abstract art, then try sending them an image of the sigil.
