I don't think anybody will think you're creepy; if they do, I honestly think they would be the weird ones. The worst case, I think, would be just that the other user (whether ttt111111 or someone else) will ignore the message you send. But I don't think very many folks ignore a DM. You might occasionally find that another user has privatized their account, in which case you wouldn't even see a Start Conversation button after clicking their name. Beyond that, as long as you avoid trolling or similar things prohibited by F95Zone, nobody should really think anything creepy, strange, or offensive about getting a DM from you.
