I see "meme" coins are clogging up Blockchains and rendering them useless, as the hype shows no signs of slowing down. Blockchains like ETH, BTC, and even Polygon/MATIC have seen an increase in network fees. Even Coinbase's ETH L2 network (BASE) have been affected by "meme" coins.
It is difficult to create a secure network of meme coins if in the end the way of making and the cost is still very cheap as well as for Base because even though it is the L2 network of ETH still at a fairly cheap price it will always be utilized by those who always make memecoins as one of the options to create schemes for personal gain 
We can't prohibit that because after all, everyone can do whatever they want including making meme coins like this because in this case what I feel is that as long as the fee costs can still be conditioned and are classified as very cheap for making meme coins then it will continue to happen no matter which network it is except if the gas costs are high like ETH maybe we will think twice about doing it.
