When using Oksender, one should be cautious, as there is no protection against blocks. The program builds a promotion strategy based on certain algorithms, suggesting that you can send a limited number of messages per day without consequences. However, in practice, things are different, and one should not ignore user complaints, as sending a hundred or two hundred messages or invites can lead to a block. I lost two accounts, and with the third one, I'm currently working more or less successfully. There are no blocks for using the program, but spam and intrusiveness can definitely lead to issues. For example, parsing and visiting pages can be done without problems, but it's not advisable to use multiple accounts too aggressively. However, sending messages and invites should be done with caution.
